Description

Technical Field

[0001] This invention relates to the field of communication engineering technology, specifically to a fixed-point mapping device for communication engineering surveying and its usage method. Background Technology

[0002] Currently, the major of communication engineering mainly studies the generation of signals, the transmission, exchange and processing of information, as well as the theoretical and engineering application problems in computer communication, digital communication, satellite communication, fiber optic communication and other fields. Communication engineering requires a large amount of data to be surveyed during the construction process in order to ensure the quality of the project. Therefore, surveying equipment is needed in the early stage.

[0003] The prior art, with publication number CN217331164U and titled "A Fixed-Point Mapping Device for Communication Engineering Survey," uses a closed area formed by the upper cover and lower shell to protect the mapping instrument from damage caused by screen breakage or dust entering the instrument upon impact.

[0004] However, when using this patent, the operator must first open the outer rod and then insert the countersunk nail into the ground, which cannot guarantee that the surveying equipment is level with the ground. If the equipment is used on uneven road surfaces, it cannot be guaranteed that the surveying equipment is level with the ground, which will lead to errors in the surveying data. At the same time, this patent is inconvenient to transport and carry, and the surveying equipment has a single function and form, and cannot be adjusted according to the user's needs to improve the convenience of the operator.

[0005] In addition, after the surveying equipment is used, it is usually disassembled and placed inside the box. When it is needed, the operator takes out the surveying equipment parts placed inside the box and reassembles and fixes them. This reduces work efficiency. Furthermore, because the equipment needs to be assembled and disassembled, it is easy to lose parts. Also, the wear and tear of the connecting parts may reduce the accuracy of the equipment. Summary of the Invention

[0006] This invention proposes a fixed-point surveying device for communication engineering surveys, which can solve the problems of surveying instruments in related technologies being unable to maintain a horizontal position and having limited functionality.

[0007] The technical solution of the present invention is as follows: a fixed-point mapping device for communication engineering survey, comprising a housing, a servo motor installed inside the housing, the output end of the servo motor being fixedly connected to a coaxially arranged rotating shaft via a coupling, and a telescopic handle being fixedly provided on the housing;

[0008] The housing contains a lifting and leveling device, a telescopic and unfolding device, and a recording platform. The lifting and leveling device includes a mapping instrument, the bottom of which is fixedly connected to a pad. The bottom of the pad is fixedly connected to a vertical rod. A horizontal plate is slidably arranged inside the housing. A first rack is fixedly connected to the bottom of the horizontal plate. A drive spur gear is fixedly sleeved on the outer circumference of the rotating shaft. The drive spur gear meshes with the first rack. A ball groove is formed inside the horizontal plate. A rotating ball is arranged inside the ball groove. The bottom end of the vertical rod is fixedly connected to the rotating ball. A lifting rod is fixedly connected to the rotating ball. A counterweight ball is fixedly connected to the bottom end of the lifting rod. A threaded rod is rotatably installed inside the horizontal plate. By screwing the threaded rod, it abuts against the rotating ball to limit its movement.

[0009] Preferably, two symmetrically arranged rotating covers are rotatably mounted on the housing. Each of the two rotating covers has a movable block fixedly connected inside, and each of the two movable blocks has a connecting block movably connected inside. Two symmetrically arranged side rods are fixedly connected to the horizontal plate, and each of the two side rods has a movable rotating rod fixedly connected to it. The movable rotating rod is movably hinged to the connecting block.

[0010] Preferably, a first rack travel limiting mechanism is provided at both ends of the first rack. Each first rack travel limiting mechanism includes two first support plates provided at the corresponding ends of the first rack. A first slide rod is fixedly connected to each of the two first support plates. A first side plate is slidably mounted on the two first slide rods. A first limiting inclined block is fixedly connected to one side of each of the first side plates. One end of each of the two first limiting inclined blocks is inclined. A first return spring is sleeved on the first slide rod. The first return spring is connected to the corresponding first support plate and the first side plate respectively.

[0011] Preferably, the telescopic deployment device includes a base plate, which is slidably disposed inside the housing. Three pneumatic-hydraulic rods arranged in a triangular pattern are rotatably mounted on the base plate. An auxiliary sleeve is fixedly fitted on the outer circumferential surface of each of the three pneumatic-hydraulic rods. A round rod is fixedly connected to the bottom of the base plate, and an active sliding sleeve is slidably fitted on the outer circumferential surface of the round rod.

[0012] The active sliding sleeve has three connecting rods arranged in a triangular pattern, and the three connecting rods are respectively hinged to the three auxiliary sleeves.

[0013] Preferably, the base plate has a through hole that penetrates itself, and a straight bar is slidably connected inside the through hole. The straight bar is fixedly connected to the active sliding sleeve, and a second rack is fixedly connected to the top of the straight bar. The second rack meshes with the active spur gear.

[0014] The second rack has a second rack travel limiting mechanism at each end. The second rack travel limiting mechanism includes two second support plates at the corresponding ends of the second rack. A second slide rod is fixedly connected to each of the two second support plates. The two second slide rods are slidably fitted with a second side plate. A second limiting block is fixedly connected to one side of each of the two second side plates. One end of each of the two second limiting blocks is inclined. A second return spring is sleeved on the outside of the second slide rod. The second return spring is connected to the second support plate and the second side plate respectively.

[0015] Preferably, the recording table device includes a windproof tabletop and a sunshade. A first rotating column is fixedly nested inside the windproof tabletop. The first rotating column is rotatably installed inside the housing. A connecting wheel is fixedly sleeved on the first rotating column. A rotating rod is rotatably installed inside the housing. A follower gear, a transmission wheel, and a stabilizing wheel are fixedly sleeved on the outer circumference of the rotating rod. A flipping synchronous belt is sleeved on the transmission wheel and the connecting wheel. A fixed rack is fixedly installed on the top of the base plate. The fixed rack meshes with the follower gear.

[0016] Preferably, a second rotating column is fixedly nested inside the sunshade, the second rotating column is rotatably installed inside the housing, an incomplete gear is fixedly provided on the sunshade, a driving gear is rotatably installed inside the housing, the driving gear meshes with the incomplete gear, a driving synchronizing pulley is fixedly connected to one side of the driving gear, and a transmission synchronizing belt is sleeved on both the driving synchronizing pulley and the stabilizing pulley.

[0017] The present invention also provides a method for using a fixed-point mapping device for communication engineering surveys, employing the aforementioned fixed-point mapping device for communication engineering surveys, with the specific steps as follows:

[0018] S1: Turn on the motor to drive the main shaft to rotate. When the drive spur gear rotates, it drives the first rack to move upward. The first rack also drives the horizontal plate, the pad plate and the mapping instrument to move upward together. The rotating ball set inside the horizontal plate rotates and adjusts its position under the drive of the counterweight and the hanging rod. The mapping instrument keeps horizontal with the ground under the drive of the upright and the rotating ball.

[0019] S2: The two side rods on the horizontal plate drive the movable rotating rod to move upward together; the connecting block pushes the rotating cover through the movable block, and the two rotating covers rotate to the sides and open at the same time.

[0020] S3: When the drive spur gear rotates, the second rack moves downward, and the rack pushes the drive sliding sleeve downward. When the drive sliding sleeve moves downward, it pushes the auxiliary sleeve through three movable hinged connecting rods. The auxiliary sleeve will drive the pneumatic hydraulic rod to unfold.

[0021] S4: The servo motor drives the second rack and the base plate to move downward together. During the downward movement, the fixed rack meshes with the follower gear and drives the follower gear to rotate. When the follower gear rotates, it drives the rotating rod to rotate together, and the transmission wheel and the stabilizing wheel rotate accordingly.

[0022] S5: When the stabilizing wheel rotates, it drives the first rotating column and the windproof table to rotate together. The windproof table rotates and opens. At the same time, when the stabilizing wheel rotates, it drives the transmission timing belt to rotate together. When the transmission timing belt rotates, it drives the drive gear to rotate. The drive gear rotates and drives the incomplete gear to rotate together. The sunshade rotates and opens under the drive of the incomplete gear.

[0023] The working principle and beneficial effects of this invention are as follows:

[0024] 1. This invention, through a lifting and leveling device and other structures, allows the mapping instrument to be used. When the servo motor is turned on, it drives the rotating shaft to rotate. The active spur gear fixed on the rotating shaft rotates simultaneously. When the active spur gear rotates, it drives the first rack meshing with it to move upward. When the first rack moves upward, it drives the horizontal plate, the pad plate, and the mapping instrument to move upward together. When the two side plates fixed on the horizontal plate move upward, they drive the movable rotating rod to move upward together. The connecting block, pushed by the movable rotating rod, drives the movable block and the rotating cover to rotate together. The two rotating covers rotate 90° simultaneously and open. At this time, the mapping instrument is lifted to the top of the housing. Because the counterweight ball is fixedly connected to the rotating ball through the hanging rod, the counterweight ball always remains perpendicular to the ground due to its own weight. During the process of the counterweight ball maintaining its verticality, the rotating ball is continuously adjusted in position by the hanging rod. The upright fixed on the rotating ball also adjusts with the rotating ball and remains horizontal to the ground. Therefore, the pad plate fixedly connected to the top of the upright and the mapping instrument installed on the top of the pad plate also remain horizontal to the ground, achieving the effect of keeping the mapping instrument horizontal.

[0025] 2. This invention, through a telescopic unfolding device and other structures, allows the following mechanism to be used when the surveying instrument is in operation: When the active spur gear rotates, it drives the second rack meshing with it to move downwards. The spur also moves downwards, causing the active sliding sleeve to move downwards as well. When the active sliding sleeve moves downwards, the three hinged connecting rods will expand outwards. When the three connecting rods expand, the three rotating support rods also expand outwards simultaneously. When the three rotating support rods are fully expanded, the bottom of the second rack contacts the top of the base plate. The second rack pushes the base plate and the three rotating support rods downwards together, achieving the effect of automatic expansion.

[0026] 3. This invention utilizes auxiliary surveying devices and other structures. When operators need to record or mark surveying data during fixed-point surveying, a recording table device is required. The specific operating steps are as follows: When the base plate moves downward, the fixed rack meshes with the follower gear. At this time, the follower gear and the rotating rod rotate together. When the rotating rod rotates, it simultaneously drives the transmission wheel and the stabilizing wheel to rotate. When the transmission wheel rotates, it causes the connecting wheel to rotate through the flipping synchronous belt. When the connecting wheel rotates, it drives the windproof table edge to rotate through the first rotating column. At this time, the windproof table flips downward 90 degrees from its original vertical state and becomes perpendicular to one side of the shell. Simultaneously, when the stabilizing wheel rotates, it causes the active synchronous wheel to rotate through the transmission synchronous belt. When the active gear fixedly installed on one side of the active synchronous wheel rotates, it drives the incomplete gear meshing with it to rotate. Because the incomplete gear is fixedly connected to the sunshade, the sunshade will flip upward 90 degrees and eventually become perpendicular to one side of the shell. The sunshade is located above the windproof table and can effectively block sunlight for the operator. Attached Figure Description

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figures 1 to 13As shown, this embodiment proposes a fixed-point mapping device for communication engineering surveys, including a housing 4. A servo motor 6 is installed inside the housing 4. The output end of the servo motor 6 is fixedly connected to a coaxially arranged rotating shaft 7 via a coupling. A telescopic handle 5 is fixedly installed on the housing 4. Inside the housing 4 are a lifting and leveling device 1, a telescopic and unfolding device 2, and a recording platform device 3. The lifting and leveling device 1 includes a mapping instrument 101. A pad 102 is fixedly connected to the bottom of the mapping instrument 101, and a vertical pole 103 is fixedly connected to the bottom of the pad 102. The housing 4... A horizontal plate 104 is slidably mounted on the horizontal plate 104. A first rack 113 is fixedly connected to the bottom of the horizontal plate 104. A drive spur gear 119 is fixedly sleeved on the outer circumference of the rotating shaft 7. The drive spur gear 119 meshes with the first rack 113. A ball groove is opened inside the horizontal plate 104. A rotating ball 120 is set inside the ball groove. The bottom end of the upright 103 is fixedly connected to the rotating ball 120. A hanging rod 105 is fixedly connected to the rotating ball 120. A counterweight ball 106 is fixedly connected to the bottom end of the hanging rod 105. A threaded rod 107 is rotatably installed inside the horizontal plate 104.

[0047] In this embodiment, the mapping instrument 101 is existing technology, and will not be described in detail here.

[0048] Two symmetrically arranged rotating covers 108 are rotatably mounted on the housing 4. Movable blocks 110 are fixedly connected inside the two rotating covers 108. Connecting blocks 111 are movably connected inside the two movable blocks 110. Two symmetrically arranged side rods 109 are fixedly connected on the horizontal plate 104. Movable rotating rods 112 are fixedly connected to the two side rods 109. The movable rotating rods 112 are movably hinged to the corresponding connecting blocks 111.

[0049] When the surveying instrument 101 is needed, the servo motor 6 is turned on. The servo motor 6 drives the rotating shaft 7 to rotate. When the drive spur gear 119 rotates, it drives the first rack 113 to move upward. When the first rack 113 moves upward, it pushes the horizontal plate 104 to move upward as well. At the same time, the rotating ball 120 set inside the horizontal plate 104 pushes the pad 102 and the surveying instrument 101 to move upward together through the upright 103. The two side rods 109 fixed on the two side plates of the horizontal plate 104 will drive the movable rotating rod 112 to move upward. The connecting block 111, which is movably hinged on the rod 112, will also be driven. Since the connecting block 111 is movably connected inside the movable block 110, the movable block 110 will be pushed upward and will simultaneously drive the rotating cover 108, which is fixedly connected to it, to rotate and open. The two rotating covers 108 will rotate 90° simultaneously. After the surveying instrument 101 is used, the servo motor 6 reverses, and the first rack 113 drives the horizontal plate 104 to move downward. The two side rods 109 fixedly set on the horizontal plate 104 will then drive the two rotating covers 108 to close automatically.

[0050] In addition, the rotating ball 120 inside the horizontal plate 104 is fixedly connected to the counterweight ball 106 through the hanging rod 105. Under its own weight, the counterweight ball 106 will adjust its center of gravity according to the inclination of the shell 4 and always remain perpendicular to the ground. At the same time, because the upright rod 103 is also fixedly connected to the counterweight ball 106, it should be noted that the upright rod 103, the hanging rod 105 and the counterweight ball 106 are on the same center line, and the weight of the counterweight ball 106 is greater than the sum of the weights of the surveying instrument and the pad 102. Therefore, the upright rod 103 will also adjust its position and drive the pad 102 and the surveying instrument to always remain horizontal to the ground. When the surveying instrument is horizontal, the operator rotates the threaded rod 107 on the horizontal plate 104. The threaded rod 107 will press the rotating ball 120 against the ground to achieve a fixing effect.

[0051] Furthermore, such as Figure 3 , 5 As shown, a first rack stroke limiting mechanism is provided at both ends of the first rack 113. Each first rack stroke limiting mechanism includes two first support plates 114 provided at the corresponding ends of the first rack 113. A first slide rod 116 is fixedly connected to each of the two first support plates 114. A first side plate 117 is slidably mounted on each of the two first slide rods 116. A first limiting inclined block 118 is fixedly connected to one side of each of the first side plates 117. One end of each of the two first limiting inclined blocks 118 is inclined. A first return spring 115 is sleeved on the first slide rod 116. The first return spring 115 is connected to the corresponding first support plate 114 and the first side plate 117 respectively.

[0052] For the first rack travel limiting mechanism at the lower end of the first rack 113, after the mapping instrument 101 is completely pushed out of the telescopic groove, the first rack 113 is pushed to the top. The driving spur gear 119 then meshes with the first limiting wedge block 118. At this time, the first limiting wedge block 118 is pushed downward by the driving spur gear 119. Because the first limiting wedge block 118 is simultaneously slidably sleeved on the two first slide rods 116, and the first return spring 115 is simultaneously connected to the first side plate 117 and the first support plate 114, when the first limiting wedge block 118 is pushed downward... The two first return springs 115 will be pulled up. After the teeth on the driving spur gear 119 separate from the first limiting block 118, the first limiting block 118 and the first side plate 117 will be reset under the action of the two first return springs 115. In this way, the first rack 113 will not continue to move upward under the force of the driving spur gear 119, thus realizing the rack limiting function. The limiting principle of the first rack stroke limiting mechanism at the upper end of the first rack 113 is the same as above. In summary, by setting the first rack stroke limiting mechanism, motion interference during use is avoided and stability is improved.

[0053] Example 2

[0054] like Figures 1 to 13As shown, based on Embodiment 1, this embodiment adds the following structure: The telescopic deployment device 2 includes a base plate 208, which is slidably disposed inside the housing 4. Three pneumatic-hydraulic rods 204 arranged in a triangular pattern are rotatably mounted on the base plate 208. Auxiliary sleeves 205 are fixedly sleeved on the outer circumferential surface of each of the three pneumatic-hydraulic rods 204. A round rod 207 is fixedly connected to the bottom of the base plate 208. An active sliding sleeve 206 is slidably assembled on the outer circumferential surface of the round rod 207. Three connecting rods 203 arranged in a triangular pattern are movably hinged on the active sliding sleeve 206. The three connecting rods 203 are movably hinged to the three auxiliary sleeves 205 respectively.

[0055] The base plate 208 has a through hole that passes through it. A straight bar 202 is slidably connected inside the through hole. The straight bar 202 is fixedly connected to the active sliding sleeve 206. A second rack 201 is fixedly connected to the top of the straight bar 202. The second rack 201 is meshed with the active spur gear 119. A second rack stroke limiting mechanism is provided at both ends of the second rack 201. The second rack stroke limiting mechanism includes two second support plates 209 set at the corresponding ends of the second rack. A second slide rod 211 is fixedly connected to each of the two second support plates 209. The two second slide rods 211 are slidably assembled with a second side plate 212. A second limiting inclined block 213 is fixedly connected to one side of each of the two second side plates 212. One end of each of the two second limiting inclined blocks 213 is inclined. A second return spring 210 is sleeved on the outside of the second slide rod 211. The second return spring 210 is connected to the second support plate 209 and the second side plate 212 respectively.

[0056] In this embodiment, during use, the operator first manually extends all three pneumatic hydraulic rods 204 (model YQL-508). Then, when the rotating shaft 7 drives the drive spur gear 119 to rotate, it causes the second rack 201 and the straight bar 202 to move downwards together. As the straight bar 202 moves downwards, it pushes the drive sleeve 206 downwards along the axis of the round rod 207. Three connecting rods 203, which are hinged to the drive sleeve 206, push the three auxiliary sleeves 205 and the three pneumatic hydraulic rods 204 outwards together. After the three pneumatic hydraulic rods 204 are fully extended, the second rack 201... The bottom of the rack 201 is in contact with the top of the base plate 208. The driving spur gear 119 continues to drive the second rack 201 to move downward. The second rack 201 pushes the base plate 208 to move downward together. Similarly, the top and bottom of the second rack 201 are provided with a second rack stroke limiting mechanism consisting of a second support plate 209, a second return spring 210, a second slide rod 211, a second side plate 212, and a second limiting wedge block 213. When the second rack 201 moves to the top or bottom, the driving spur gear 119 will contact the second limiting wedge block 213, but will not cause the second rack 201 to continue moving, thus achieving the limiting function.

[0057] In this embodiment, in order to improve the portability and ease of use of the fixed-point mapping equipment, when the fixed-point mapping equipment is not in working condition, both the mapping instrument 101 and the pneumatic hydraulic rod 204 are retracted into the telescopic groove opened inside the housing 4, thereby achieving the effect of easy movement.

[0058] Example 3

[0059] like Figures 1 to 13 As shown, based on Embodiment 1 or Embodiment 2, this embodiment adds the following structure: The recording table device 3 includes a windproof table 306 and a sunshade 301. A first rotating column 312 is fixedly nested inside the windproof table 306. The first rotating column 312 is rotatably installed inside the housing 4. A connecting wheel 309 is fixedly sleeved on the first rotating column 312. A rotating rod 307 is rotatably installed inside the housing 4. A follower gear 308, a transmission wheel 314, and a stabilizing wheel 311 are fixedly sleeved on the outer circumference of the rotating rod 307. The transmission wheel 314 and the connecting wheel 309 are jointly sleeved with a flipping synchronous belt 315. A fixed rack 310 is fixedly installed on the top of the base plate 208. The fixed rack 310 is meshed with the follower gear 308.

[0060] The sunshade 301 has a second rotating column 313 fixedly nested inside. The second rotating column 313 is rotatably installed inside the housing 4. An incomplete gear 302 is fixedly installed on the sunshade 301. A drive gear 303 is rotatably installed inside the housing 4. The drive gear 303 meshes with the incomplete gear 302. A drive synchronous pulley 304 is fixedly connected to one side of the drive gear 303. The drive synchronous pulley 304 and the stabilizing pulley 311 are together fitted with a transmission synchronous belt 305.

[0061] When operators need to record or mark survey data during fixed-point mapping, a recording table device is required. The specific operating steps are as follows: When the base plate 208 moves downward, the fixed rack 310 will mesh with the follower gear 308. At this time, the follower gear 308 and the rotating rod 307 rotate together. When the rotating rod 307 rotates, it will simultaneously drive the transmission wheel 314 and the stabilizing wheel 311 to rotate together. When the transmission wheel 314 rotates, it will cause the connecting wheel 309 to rotate by flipping the synchronous belt 315. When the connecting wheel 309 rotates, it will drive the windproof table 306 to rotate by the first rotating column 312. At this time, the windproof table 306 will flip downward from its original vertical state. The sunshade 301 is perpendicular to one side of the housing 4 at a 90-degree angle. When the stabilizing wheel 311 rotates, it causes the driving synchronous wheel 304 to rotate through the transmission synchronous belt 305. When the driving synchronous wheel 304 rotates, it drives the driving gear 303 to rotate, which in turn drives the incomplete gear 302 that meshes with it. Because the incomplete gear 302 is fixedly connected to the sunshade 301, the sunshade 301 will rotate upwards by 90 degrees and eventually become perpendicular to one side of the housing 4. The sunshade 301 is located above the windproof table 306. The notebook or other recording computer can be placed on the windproof table 306. The sunshade 301 can effectively block sunlight for the recording operator.

[0062] Example 4

[0063] A method for using a fixed-point mapping device for communication engineering surveying, employing the fixed-point mapping device for communication engineering surveying in Example 3, includes the following specific steps:

[0064] S1: When the motor is turned on, the main shaft rotates. When the drive spur gear 119 rotates, it drives the first rack 113 to move upward. The first rack 113 simultaneously drives the horizontal plate 104, the pad plate 102, and the mapping instrument 101 to move upward together. The rotating ball 120 set inside the horizontal plate 104 rotates and adjusts its position under the drive of the counterweight and the hanging rod 105. The mapping instrument 101 remains horizontal with the ground under the drive of the upright rod 103 and the rotating ball 120.

[0065] S2: The two side rods 109 on the horizontal plate 104 drive the movable rotating rod 112 to move upward together; the connecting block 111 pushes the rotating cover 108 through the movable block 110, and the two rotating covers 108 rotate to the sides and open at the same time.

[0066] S3: When the drive spur gear 119 rotates, the second rack 201 moves downward, the spur 202 pushes the drive sliding sleeve 206 to move downward, and when the drive sliding sleeve 206 moves downward, it pushes the auxiliary sleeve 205 through the three movable hinged connecting rods 203, and the auxiliary sleeve 205 drives the pneumatic hydraulic rod 204 to unfold.

[0067] S4: The servo motor 6 drives the second rack 201 and the base plate 208 to move downward together. During the downward movement, the fixed rack 310 meshes with the follower gear 308 and drives the follower gear 308 to rotate. When the follower gear 308 rotates, it drives the rotating rod 307 to rotate together, and the transmission wheel 314 and the stabilizing wheel 311 rotate accordingly.

[0068] S5: When the stabilizing wheel 311 rotates, it drives the first rotating column 312 and the windproof table 306 to rotate together. The windproof table 306 rotates and opens. At the same time, when the stabilizing wheel 311 rotates, it drives the transmission timing belt 305 to rotate together. When the transmission timing belt 305 rotates, it drives the drive gear 303 to rotate. The drive gear 303 rotates and drives the incomplete gear 302 to rotate together. The sunshade 301 rotates and opens under the drive of the incomplete gear 302.

[0069] In this embodiment, the base plate 208 moves downward under the push of the second rack 201. During the downward movement of the fixed rack 310, it will mesh with the follower gear 308. The follower gear 308 rotates and drives the transmission rod to rotate together. When the transmission wheel 314 rotates, it drives the sleeve wheel 309 to rotate through the flipping synchronous belt 315. Because the sleeve wheel 309 is fixedly connected to the windproof table 306 through the first rotating column 312, the windproof table 306 is flipped downward by 90° under the drive of the first rotating column 312 and is perpendicular to one side of the housing 4. When the stabilizing wheel 311 rotates, it drives the transmission rod to rotate. The drive synchronous belt 305 drives the drive synchronous pulley 304 to rotate. Since a drive gear 303 is fixedly installed on one side of the drive synchronous pulley 304, the drive gear 303 will also rotate. When the drive gear 303 rotates, it will drive the incomplete gear 302 that meshes with it to rotate. Since the incomplete gear 302 is fixedly connected to the sunshade 301, the sunshade 301 will also rotate. The sunshade 301 will rotate upward 90° and be inclined to one side of the housing 4. The sunshade 301 is located above the windproof table 306 and can play the role of blocking sunlight.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
