The outer wall of the threaded rod is threadedly connected to the inner wall of the extension column, and the protrusion of the extension column is embedded in the closed thread groove of the threaded rod. The rotation of the threaded rod drives the extension column to reciprocate.

[0010] A further improvement of the technical solution of the present invention is as follows: a linkage bevel gear rod is rotatably connected to the center of one side of the inner wall of the regulating chamber, and one side of the outer wall of the linkage bevel gear rod meshes with the outer wall of the transmission bevel gear rod. A contact block is fixedly connected to the side of the outer wall of the linkage bevel gear rod away from the transmission bevel gear rod. A limit box is fixedly connected to the side of the outer wall of the regulating chamber near the linkage bevel gear rod, and a limit plate is slidably connected to the inner wall of the limit box. A storage box is fixedly connected to the inner cavity of the limit plate. Both ends of the inner wall of the storage box are fixedly connected to elastic telescopic rods, and the output ends of the elastic telescopic rods are fixedly connected to fitting blocks. A locking block is fixedly connected to one side of the outer wall of the fitting block, and the outer wall of the locking block contacts the limit wheel. One side of the outer wall of the limit wheel is fixedly connected to the side of the outer wall of the linkage bevel gear rod near the contact block.

[0011] A further improvement of the technical solution of the present invention is that: one side of the outer wall of the contact block is in contact with an adjustment block, and the two ends of the outer wall of the adjustment block are provided with extension grooves, and the inner wall of the extension groove is slidably connected to the center of the outer wall of the fitting block, and an installation tube is fixedly connected to the side of the outer wall of the adjustment block away from the contact block.

[0012] A further improvement of the technical solution of the present invention is that: a battery is slidably connected to the top of one side of the inner wall of the fixed compartment, and a wire is installed at the bottom of the battery, with one end of the wire being installed at the top of the monitor.

[0013] A further improvement of the technical solution of the present invention is that: a plurality of sliding grooves are provided at the bottom of the inner cavity of the fixed chamber, and a clamping rod is slidably connected to the inner wall of the sliding groove, and one end of the clamping rod is clamped to the outer wall of the monitor; a turntable is rotatably connected to the bottom of the inner wall of the fixed chamber, and a plurality of limiting grooves are provided in the inner cavity of the turntable; a guide rod is slidably connected to the inner wall of the limiting groove, and one end of the guide rod is fixedly connected to the top of the clamping rod.

[0014] A further improvement of the technical solution of the present invention is that: a fixing block is fixedly connected to one side of the outer wall of the turntable, and an elastic rod is slidably connected to the inner cavity of the fixing block, while a pull ring is fixedly connected to one end of the outer wall of the elastic rod.

[0015] A further improvement of the technical solution of the present invention is that: a slot is provided on one side of the outer wall of the fixed chamber, and a plug is inserted into the inner wall of the slot, and the bottom of the plug is fixedly connected to the top of the outer wall of the elastic rod.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0017] 1. This invention provides an IoT-based monitoring rack. By embedding a closed threaded groove of a threaded rod into the protrusion of the extension column, the threaded rod controls the extension column to drive the fixed mounting frame, mounting block, fixing compartment, and monitor to move upward along the limit of the inner wall of the limiting shell. This further solves the problems of traditional IoT monitoring racks, which are not only cumbersome to install, but also inconvenient to clean and maintain the monitoring device afterward.

[0018] 2. This invention provides an IoT-based monitoring rack. By setting a contact block on the outer wall of the linkage bevel gear rod away from the transmission bevel gear rod, the contact block limits the adjustment block inserted into the storage box, preventing the adjustment block from going too deep and causing misalignment of the locking block, and preventing the linkage bevel gear rod from rotating through the limit wheel. This further solves the problem that in the use of traditional IoT monitoring racks, the rack structure is relatively simple due to the need for regular cleaning and maintenance, which makes it easy for the monitoring device to be stolen or damaged.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 9 As shown in the embodiment of the present invention, a monitoring rack based on the Internet of Things includes a base 1. An adjustment chamber 2 is fixedly connected to the top of the base 1, and a limiting shell 3 is fixedly connected to the top of the adjustment chamber 2. An adjustment component is provided on the inner wall of the adjustment chamber 2. An extension column 4 is slidably connected to the inner wall of the limiting shell 3, and a mounting frame 5 is rotatably connected to the top of the extension column 4. A mounting block 6 is rotatably connected to one end of the mounting frame 5, and a fixing chamber 7 is threadedly connected to the outer wall of the mounting block 6. A monitor 8 is installed on the inner wall of the fixing chamber 7. The adjustment component includes a transmission bevel gear rod 9 rotatably connected to the center of the bottom of the inner wall of the adjustment chamber 2, and a threaded rod 10 is fixedly connected to the top of the transmission bevel gear rod 9. The outer wall of the threaded rod 10 is threadedly connected to the inner wall of the extension column 4, and the protrusion of the extension column 4 is embedded in the closed threaded groove of the threaded rod 10. The rotation of the threaded rod 10 drives the extension column 4 to reciprocate.

[0031] During operation, an adjustment chamber 2 is set on the top of the base 1, and a limiting shell 3 is set on the top of the adjustment chamber 2. An extension column 4 is set on the inner wall of the limiting shell 3, and the mounting bracket 5 set on the top of the extension column 4 is pulled. Using the mounting block 6 set on one end of the mounting bracket 5, the fixing chamber 7 with the monitor 8 is installed on the outer wall of the mounting block 6. Then, the screw set between the mounting block 6 and the mounting bracket 5 is rotated to fix them (this is prior art, refer to the fan connection). Then, the mounting bracket 5 is pushed again, and the screw set between the mounting bracket 5 and the extension column 4 is rotated to fix them (this is prior art, refer to the fan connection). This completes the initial installation of the monitor placement frame. At this time, the mounting tube 22 set on one side of the outer wall of the adjustment block 20 is used, and the mounting tube 22 is installed on the output end of the electric drill. The operator holds the electric drill and inserts the mounting tube 22 together with the adjustment block 20 into the limiting box 13. The outer wall of the adjustment block 20 passes through the storage box 15 and pushes the fitting block set on the inner wall of the storage box 15. 17 Simultaneously, and in contact with the surface of the contact block 12, the electric drill is started and drives the adjusting block 20 and the mounting tube 22 to rotate within the limit box 13, causing the locking block 18 on one side of the outer wall of the fitting block 17 to drive the limit wheel 19 to rotate. Since a linkage bevel gear rod 11 is provided on one side of the outer wall of the limit wheel 19, and a transmission bevel gear rod 9 is provided at the center of the bottom of the inner wall of the adjusting chamber 2, and the transmission bevel gear rod 9 meshes with the linkage bevel gear rod 11, the linkage bevel gear rod 11 drives the threaded rod 10 provided at the top of the transmission bevel gear rod 9 to rotate. Since the protrusion of the extension column 4 is embedded in the closed thread groove of the threaded rod 10, the threaded rod 10 controls the extension column 4 to drive the fixed mounting frame 5, mounting block 6, fixing chamber 7 and monitor 8 to move upward along the limit of the inner wall of the limit shell 3. This further solves the problem that traditional IoT monitoring placement racks are not only cumbersome to install, but also inconvenient to clean and maintain the monitoring device later.

[0032] A linkage bevel gear rod 11 is rotatably connected to the center of one side of the inner wall of the regulating chamber 2, and one side of the outer wall of the linkage bevel gear rod 11 meshes with the outer wall of the transmission bevel gear rod 9. A contact block 12 is fixedly connected to the side of the outer wall of the linkage bevel gear rod 11 away from the transmission bevel gear rod 9. A limit box 13 is fixedly connected to the side of the outer wall of the regulating chamber 2 near the linkage bevel gear rod 11, and a limit plate 14 is slidably connected to the inner wall of the limit box 13. A storage box 15 is fixedly connected to the inner cavity of the limit plate 14, and an elastic telescopic rod 16 is fixedly connected to both ends of the inner wall of the storage box 15. Each output end of the telescopic rod 16 is fixedly connected to a fitting block 17. A locking block 18 is fixedly connected to one side of the outer wall of each fitting block 17. The outer wall of the locking block 18 contacts a limiting wheel 19. One side of the outer wall of the limiting wheel 19 is fixedly connected to the side of the outer wall of the linkage bevel gear rod 11 near the contact block 12. One side of the outer wall of the contact block 12 contacts an adjusting block 20. Extension grooves 21 are provided at both ends of the outer wall of the adjusting block 20. The inner wall of the extension groove 21 is slidably connected to the center of the outer wall of the fitting block 17. An installation tube 22 is fixedly connected to the side of the outer wall of the adjusting block 20 away from the contact block 12.

[0033] During operation, a limiting box 13 is installed on one side of the outer wall of the adjusting chamber 2, and a limiting plate 14 is installed on the inner wall of the limiting box 13. A storage box 15 is installed inside the cavity of the limiting plate 14. When the mounting tube 22 on one side of the outer wall of the adjusting block 20 is fixed to the output end of the electric drill, the mounting tube 22 and the adjusting block 20 are inserted into the limiting box 13 and attached to the outer wall of the contact block 12. Since the two ends of the inner wall of the storage box 15 are provided with elastic telescopic rods 16, and the output ends of the elastic telescopic rods 16 are provided with fitting blocks 17, the outer wall of the adjusting block 20 pushes the fitting blocks 17 at both ends to slide on the inner wall of the storage box 15, and the locking block 18 on one side of the outer wall of the fitting block 17 is embedded into the limiting wheel 1 on one side of the outer wall of the linkage bevel gear rod 11. Inside 9, because one side of the outer wall of the linkage bevel gear rod 11 meshes with one side of the outer wall of the transmission bevel gear rod 9, the electric drill is started at this time. The adjustment block 20 is driven through the installation tube 22. The extension grooves 21 are provided at both ends of the outer wall of the adjustment block 20. At the same time, the protrusion provided at the center of the outer wall of the fitting block 17 is fitted, and the storage box 15 is driven to rotate in the limiting box 13. The linkage bevel gear rod 11 is driven to drive the transmission bevel gear rod 9. The extension column 4 is raised and lowered by the threaded rod 10. The limiting plate 14 provided on the outer wall of the storage box 15 rotates in the limiting box 13 to prevent the storage box 15 from shifting during the rotation, which would cause the locking block 18 to be misaligned in the limiting wheel 19 and cause damage to the internal parts.

[0034] It should be reiterated that when others attempt to steal the monitoring device by inserting a stick-like object into the storage box 15 and pushing the interlocking block 17, the protrusion at the center of the outer wall of the interlocking block 17 causes the thicker stick-like object to over-contract when it moves the interlocking block 17, as the force point is the protrusion of the interlocking block 17. Since the adjustment chamber 2 has an additional groove on the side near the limiting wheel 19, the locking block 18 on the outer wall of the interlocking block 17 disengages from the limiting wheel 19 and embeds into the additional groove on the outer wall of the adjustment chamber 2, making it impossible to control the limiting wheel 19 and causing the extension column 4 to descend. When a thinner stick-like object is used to squeeze the two sides of the interlocking block 17 at the protrusion and control the extension column 4 to descend, the extension column 4 is heavy due to the mounting bracket 5 and other components on its top. The thinner stick-like object, with its low hardness, cannot effectively and stably limit the interlocking blocks 17 at both ends of the storage box 15 at the same time.

[0035] Furthermore, by setting a contact block 12 on the outer wall of the linkage bevel gear rod 11 away from the transmission bevel gear rod 9, the contact block 12 limits the adjustment block 20 inserted into the storage box 15, preventing the adjustment block 20 from going too deep, causing the locking block 18 to be misaligned, and preventing the linkage bevel gear rod 11 from rotating through the limit wheel 19. This further solves the problem that in the process of using traditional IoT monitoring racks, the rack structure is relatively simple due to the need for regular cleaning and maintenance, which makes it easy for the monitoring device to be stolen or damaged.

[0036] A battery 23 is slidably connected to the top of one side of the inner wall of the fixed compartment 7, and a wire 24 is installed at the bottom of the battery 23. One end of the wire 24 is installed at the top of the monitor 8. Several sliding grooves 25 are formed at the bottom of the inner cavity of the fixed compartment 7, and a clamping rod 26 is slidably connected to the inner wall of the sliding groove 25. One end of the clamping rod 26 is clamped to the outer wall of the monitor 8. A turntable 27 is rotatably connected to the bottom of the inner wall of the fixed compartment 7, and several limiting grooves 28 are formed in the inner cavity of the turntable 27. A guide rod 29 is slidably connected to the inner wall of the groove 28, and one end of the guide rod 29 is fixedly connected to the top of the clamping rod 26. A fixing block 30 is fixedly connected to one side of the outer wall of the turntable 27, and an elastic rod 31 is slidably connected to the inner cavity of the fixing block 30. A pull ring 32 is fixedly connected to one end of the outer wall of the elastic rod 31. A slot 33 is opened on one side of the outer wall of the fixing chamber 7, and an insert block 34 is inserted into the inner wall of the slot 33. The bottom of the insert block 34 is fixedly connected to the top of the outer wall of the elastic rod 31.

[0037] During operation, the battery 23 is installed on the top of one side of the inner wall of the fixed compartment 7. Then, the wire 24 on the top of the monitor 8 is connected to the output end of the battery 23. The wire 24 is then coiled up, and the base of the monitor 8 is inserted into the bottom of the inner wall of the fixed compartment 7. A slot 33 is provided on one side of the outer wall of the fixed compartment 7, and the insert block 34 provided on the inner wall of the slot 33 is pulled, so that the insert block 34 drives the elastic rod 31 to extend out from the outer wall of the fixed block 30. Since a turntable 27 is provided at the bottom of the inner wall of the fixed compartment 7 and the turntable 27 is connected to the fixed block 30, and since several sliding grooves 25 are provided at the bottom of the inner cavity of the fixed compartment 7, and each sliding groove 25 has a clamping rod 26 on its inner wall, and one end of the clamping rod 26 is provided with a clamping rod 26. With the guide rod 29, the turntable 27 loses the limit of the slot 33 and rotates in the fixed chamber 7 by pulling the fixing block 30. The limiting groove 28 in the inner cavity of the turntable 27 pushes the guide rod 29 to move in the slide groove 25, and makes one end of the clamping rod 26 fit tightly against the outer wall of the monitor 8. Moreover, the contact point between the clamping rod 26 and the monitor 8 is made of anti-slip rubber material, so as to avoid damage to the surface of the monitor 8 during the clamping process and prevent the monitor 8 from falling off between the clamping rods 26. At this time, the insert block 34 is released, and the elasticity of the elastic rod 31 is used to make the insert block 34 re-insert into the slot 33, thereby fixing the monitor 8 and facilitating the disassembly of the monitor 8 later.

[0038] The working principle of this IoT-based monitoring rack will be explained in detail below.

[0039] like Figures 1-9As shown, by setting an adjustment chamber 2 on the top of the base 1, and a limiting shell 3 on the top of the adjustment chamber 2, and by setting an extension column 4 on the inner wall of the limiting shell 3, and pulling the mounting bracket 5 set on the top of the extension column 4, the fixing chamber 7 with the monitor 8 is installed on the outer wall of the mounting block 6 using the mounting block 6 set at one end of the mounting bracket 5. Then, the screw set between the mounting block 6 and the mounting bracket 5 is rotated to fix them (this is prior art, refer to the fan connection). Then, the mounting bracket 5 is pushed again, and the screw set between the mounting bracket 5 and the extension column 4 is rotated to fix them (this is prior art, refer to the fan connection), thus completing the initial installation of the monitor placement frame. At this time, the mounting tube 22 set on one side of the outer wall of the adjustment block 20 is used, and the mounting tube 22 is installed on the output end of the electric drill. The operator holds the electric drill and inserts the mounting tube 22 together with the adjustment block 20 into the limiting box 13, and the outer wall of the adjustment block 20 passes through the storage box 15, pushing the fitting block 1 set on the inner wall of the storage box 15. 7. Simultaneously, and in contact with the surface of the contact block 12, the electric drill is started and drives the adjusting block 20 and the mounting tube 22 to rotate within the limit box 13, causing the locking block 18 on one side of the outer wall of the fitting block 17 to drive the limit wheel 19 to rotate. Since a linkage bevel gear rod 11 is provided on one side of the outer wall of the limit wheel 19, and a transmission bevel gear rod 9 is provided at the center of the bottom of the inner wall of the adjusting chamber 2, and the transmission bevel gear rod 9 meshes with the linkage bevel gear rod 11, the linkage bevel gear rod 11 drives the threaded rod 10 provided at the top of the transmission bevel gear rod 9 to rotate. Since the protrusion of the extension column 4 is embedded in the closed thread groove of the threaded rod 10, the threaded rod 10 controls the extension column 4 to drive the fixed mounting frame 5, mounting block 6, fixing chamber 7 and monitor 8 to move upward along the limit of the inner wall of the limit shell 3. This further solves the problem that traditional IoT monitoring placement racks are not only cumbersome to install, but also inconvenient to clean and maintain the monitoring device later.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
