[0008] To achieve the above objectives, the present invention adopts the following technical solution: A voltage feedback monitoring instrument includes a housing, a cover hinged to one side of the housing, a lifting plate connected to the inside of the housing via a lifting mechanism, and a monitoring instrument body fixed to the top of the lifting plate. The lifting plate is movably connected to the box body via a telescopic guide rod; The lifting unit includes a telescopic transmission assembly, a speed-increasing assembly, and a drive assembly. The telescopic transmission assembly and the speed-increasing assembly are driven by a first twisted rope, and the drive assembly and the speed-increasing assembly are driven by a second twisted rope. The lifting plate consists of a lifting plate and two extension plates slidably connected to both sides of the lifting plate via guide rods, with a spring fastened between the two guide rods; The telescopic transmission assembly includes a guide housing fixed to the inner wall of the box and a "T"-shaped slide rod fixedly installed at the bottom of the lifting plate. The "T"-shaped slide rod is slidably connected to the inner side of the guide housing, and a spring is fastened between the "T"-shaped slide rod and the guide housing. A lifting block is movably fitted to the outer wall of the "T"-shaped slide rod, and the two ends of the lifting block are movably connected to the bottom of the two extension plates respectively through connecting rods. The spring 2 has a greater spring constant than the spring 1; The monitoring instrument body consists of three monitoring units, which are respectively fixed to the outer walls of the lifting plate and the two expansion plates.

[0009] Preferably, the speed-increasing component includes a support plate fixed inside the housing, a gear ring rotatably connected to the inner side of the support plate, planetary gears meshing with the inner side of the gear ring, and a sun gear meshing with the inner side of the planetary gears.

[0010] Furthermore, a torsion spring is provided between the toothed ring and the support plate.

[0011] Based on the aforementioned scheme: the planetary gears are rotatably connected to the inner wall of the support plate via a rotating shaft; a reel is fixed to the inner wall of the sun gear; the first rope is wound around the outer wall of the reel, and the movable end of the first rope is fixed to the bottom outer wall of the lifting block. A more preferred embodiment of the aforementioned scheme is: the drive assembly includes a drum and a hinge shaft; the first hinge shaft is fixed to the inner wall of the cover and rotatably connected to the inner wall of the housing; the drum is fixedly installed on the outer wall of the first hinge shaft.

[0012] As a further embodiment of the present invention: one end of the second rope is wound around the outer wall of the drum, and the other end of the second rope is wound around the outer wall of the toothed ring.

[0013] Meanwhile, a handle is provided on one side of the box.

[0014] As a preferred embodiment of the present invention: the side wall of the box body is provided with a locking block for locking the box lid, and the side wall of the box lid is provided with a lock cylinder that cooperates with the locking block.

[0015] Meanwhile, a second hinge shaft is fixed to the top of the box body, the box cover is rotatably connected to the outer wall of the second hinge shaft, and two sets of locking blocks are slidably connected to the inner wall of the box cover.

[0016] As a preferred embodiment of the present invention: the inner wall of the box cover is provided with a slot, a locking rod is slidably inserted into the inner wall of the slot, and a button is fixedly installed on the top outer wall of the locking rod.

[0017] The beneficial effects of this invention are as follows: 1. This invention, by setting up a box and a box cover, can provide enclosed protection for the monitoring device body, thereby increasing the safety of carrying it. In addition, the lifting plate can also drive the monitoring device body to rise and fall, which can increase the operating space when connecting wire harnesses and connectors.

[0018] 2. This invention, by setting up a telescopic transmission component, cleverly utilizes the relationship between the progress coefficients of spring one and spring two, and combines the connection relationship between the components, thereby realizing the integrated lifting drive of the lifting plate and the extension plate, and the extension drive of the extension plate relative to the lifting plate, while also ensuring the motion sequence when the two are integrated, thereby reducing the power source setup and increasing the compactness of the structure.

[0019] 3. The present invention, by setting up a drive component, uses the rotation and opening of the cover as power to control the lifting and lowering of the lifting plate and the opening and closing of the extension plate relative to the lifting plate, thereby saving the arrangement of other power sources, increasing the synchronous linkage of the device, simplifying the operation steps, and improving efficiency.

[0020] 4. By setting up an acceleration component and utilizing the speed-changing relationship between the gear ring, planetary gears, and support plate, the small rotation angle change when the box cover is opened and closed can be multiplied to the rotational motion of the scroll, thereby amplifying the lifting stroke of the lifting plate and the extension plate, and the extension stroke of the extension plate relative to the lifting plate, further increasing the convenience of subsequent operation.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0025] Example 1: A voltage feedback monitoring instrument, such as Figure 1-8 As shown, it includes a housing 1, a housing cover 5 that is movably hinged to one side of the housing 1, a lifting plate 2 that is connected to the inside of the housing 1 through a lifting part 4, and a monitoring instrument body 3 that is fixed to the top of the lifting plate 2. The lifting plate 2 is movably connected to the housing 1 through a telescopic guide rod 8.

[0026] The lifting unit 4 includes a telescopic transmission assembly 9, a speed-increasing assembly 11, and a drive assembly 13. The telescopic transmission assembly 9 and the speed-increasing assembly 11 are driven by a first twisted rope 10, and the drive assembly 13 and the speed-increasing assembly 11 are driven by a second twisted rope 12.

[0027] The lifting plate 2 consists of a lifting plate 14 and two extension plates 16 slidably connected to both sides of the lifting plate 14 via guide rods 15. A spring 17 is fastened between the two guide rods 15.

[0028] The telescopic transmission assembly 9 includes a guide housing 20 fixed to the inner wall of the housing 1 and a "T"-shaped slide rod 18 fixed to the bottom of the lifting plate 14 by bolts. The "T"-shaped slide rod 18 is slidably connected to the inner side of the guide housing 20, and a spring 19 is fastened between the "T"-shaped slide rod 18 and the guide housing 20. A lifting block 21 is movably fitted to the outer wall of the "T"-shaped slide rod 18. The two ends of the lifting block 21 are movably connected to the bottom of the two extension plates 16 by connecting rods 22.

[0029] The spring 2 19 has a greater spring constant than the spring 1 17.

[0030] The monitoring unit 3 consists of three monitoring units, which are respectively fixed to the outer walls of the lifting plate 14 and the two expansion plates 16. The monitoring unit is simply the internal electrical components of the monitoring unit 3 as a whole, which are divided into three groups and fixed by three shells respectively. The three monitoring units are connected by an integrated wiring harness for power supply and signal connection. All of the above are well known technologies to those skilled in the art, and will not be described in detail in this embodiment.

[0031] When using this device, the cover 5 can be opened, and the lifting plate 2 can be pushed out as a whole by the lifting part 4. Then the two extension plates 16 can be moved to the sides respectively. Then the three monitoring units can be used for monitoring. After use, the two extension plates 16 are retracted, and then the lifting plate 2 is lowered into the inside of the box 1. Then the cover 5 can be closed.

[0032] This device, by setting up a housing 1 and a housing 5, can provide enclosed protection for the monitoring instrument body 3, thereby increasing the safety of carrying it. In addition, the lifting plate 2 can also drive the monitoring instrument body 3 to rise and fall, which can increase the operating space when connecting wire harnesses and connectors. At the same time, the monitoring instrument body 3 is set as a combination of three monitoring units, and the lifting plate 2 is a combination of lifting plate 14 and extension plate 16, which can also be expanded laterally to further increase the operating space and increase the convenience of use.

[0033] To solve the lifting control problem; such as Figure 4-7 As shown, the speed-increasing component 11 includes a support plate 25 fixed inside the housing 1, a gear ring 23 rotatably connected to the inner side of the support plate 25, a planetary gear 24 meshing with the inner side of the gear ring 23, and a sun gear 26 meshing with the inner side of the planetary gear 24. A torsion spring is provided between the gear ring 23 and the support plate 25.

[0034] The planetary gear 24 is rotatably connected to the inner wall of the support plate 25 via a rotating shaft. The inner wall of the sun gear 26 is fixed with a spool 27. The rope 10 is wound around the outer wall of the spool 27, and the movable end of the rope 10 is fixed to the bottom outer wall of the lifting block 21.

[0035] The drive assembly 13 includes a drum 28 and a hinge shaft 29. The hinge shaft 29 is fixed to the inner wall of the cover 5 and is rotatably connected to the inner wall of the housing 1. The drum 28 is welded to the outer wall of the hinge shaft 29. One end of the second rope 12 is wound around the outer wall of the drum 28, and the other end of the second rope 12 is wound around the outer wall of the toothed ring 23.

[0036] When the lid 5 is relatively open, the hinge shaft 29 and the drum 28 rotate relative to each other, thereby driving the gear ring 23 to rotate via the second rope 12. This, in turn, drives the sun gear 26 to rotate via the planetary gear 24, which in turn drives the shaft 27 to rotate. This causes the gear ring 23 to unwind the first rope 10. At this time, because the spring constant of the second spring 19 is greater than that of the first spring 17, the second spring 19 will rebound first, causing the "T"-shaped slide bar 18 to rise. This, in turn, drives the lifting plate 14 and the extension plate 16 to rise synchronously until the lifting plate 14 and the extension plate 16 slide out of the inside of the box 1. At this point, the "T"-shaped slide bar 18 has reached its travel limit. At this time, the lid 5 is not yet fully open. Continue to open it, so that the first rope 10 will continue to unwind, and the first spring 17 will rebound, so that the extension plate 16 will open to both sides until the lid 5 is fully open and the extension plate 16 is fully extended. After use, the lid 5 is rotated in the opposite direction, so that the first rope 10 is wound up, thereby pulling the lifting block 21 down. Since the spring coefficient of the second spring 19 is greater than that of the first spring 17, the first spring 17 will contract first. After the extension plate 16 is in contact with the lifting plate 14, the first rope 10 continues to wind up, so that the lifting plate 14 and the extension plate 16 descend as a whole until the lid 5 is completely closed and the lifting plate 14 and the extension plate 16 are completely retracted.

[0037] This device, by setting up a telescopic transmission component 9, cleverly utilizes the progress coefficient relationship between spring 17 and spring 29, and combines the connection relationship between the components, thereby realizing the integrated lifting drive of the lifting plate 14 and the extension plate 16, and the extension drive of the extension plate 16 relative to the lifting plate 14, and also ensuring the motion sequence when the two are integrated, thereby reducing the power source setup and increasing the compactness of the structure.

[0038] In addition, this device uses a drive assembly 13, which uses the rotation and opening of the cover 5 as power to control the lifting and lowering of the lifting plate 14 and the extension plate 16, and the opening and closing of the extension plate 16 relative to the lifting plate 14. This saves the need for other power sources, increases the synchronization of the device, simplifies the operation steps, and improves efficiency.

[0039] Based on the above, this device, by setting up a speed-increasing component 11, utilizes the speed-changing relationship between the gear ring 23, planetary gear 24, and support plate 25 to multiply the small rotation angle change when the box cover 5 is opened and closed to the rotational motion of the scroll 27. This enables the lifting stroke of the lifting plate 14 and the extension plate 16, as well as the expansion stroke of the extension plate 16 relative to the lifting plate 14, to be amplified, further increasing the convenience of subsequent operation.

[0040] A handle 6 is provided on one side of the box body 1. The handle 6 can be fixedly connected to the box body 1 or rotated.

[0041] The side wall of the box body 1 is provided with a locking block 7 for locking the box cover 5, and the side wall of the box cover 5 is provided with a lock cylinder that cooperates with the locking block 7.

[0042] In this embodiment, during use, the locking block 7 is first engaged and locked. Then, the cover 5 is rotated to open it. The hinge shaft 29 rotates relative to the drum 28, thereby driving the toothed ring 23 to rotate via the second rope 12. This, in turn, drives the sun gear 26 to rotate via the planetary gear 24, which in turn drives the drum 27 to rotate. This causes the toothed ring 23 to unwind the first rope 10. At this time, because the spring constant of the second spring 19 is greater than that of the first spring 17, the second spring 19 will rebound first, causing the "T"-shaped slide bar 18 to rise. This, in turn, drives the lifting plate 14 and the extension plate 16 to rise synchronously until the lifting plate 14 and the extension plate 16 slide out of the inside of the box 1. At this time, the "T"-shaped slide bar 18 slides to its travel limit. At this point, the cover 5 is not yet fully open. Continue to open it, so that the first rope 10 will continue to unwind, and the first spring 17 will rebound, so that the extension plate 16 will open to both sides until the box cover 5 is fully open and the extension plate 16 is fully extended. After use, the box cover 5 is rotated in the opposite direction, so that the first rope 10 is wound up, thereby pulling down the lifting block 21. Since the spring coefficient of the second spring 19 is greater than that of the first spring 17, the first spring 17 will contract first. After the extension plate 16 is in contact with the lifting plate 14, the first rope 10 continues to wind up, so that the lifting plate 14 and the extension plate 16 descend as a whole until the box cover 5 is completely closed and the lifting plate 14 and the extension plate 16 are completely retracted. Then, it is locked by the locking block 7 and the lock cylinder, and can be carried by the handle 6.

[0043] Example 2: A voltage feedback monitoring instrument, such as Figure 8 As shown, in order to solve the position locking problem, this embodiment makes the following improvements based on embodiment 1: The top of the box body 1 is fixed with a second hinge shaft 30, the box cover 5 is rotatably connected to the outer wall of the second hinge shaft 30, and the inner wall of the box cover 5 is slidably connected with two sets of locking blocks 32. The locking blocks 32 are connected to the second hinge shaft 30 through a third spring 31. The inner wall of the box cover 5 is provided with a slot 33, and a locking rod 34 is slidably inserted into the inner wall of the slot 33. A button 35 is fixed to the top outer wall of the locking rod 34 by bolts.

[0044] In this embodiment, when the lid 5 is opened from the closed state or closed from the open state, the button 35 can be pressed to cause the slot 33 to squeeze the block 32, and the block 32 is stored inside the hinge shaft 30. Thus, the lid 5 can rotate relative to the box body 1. After rotating to the fully open state or the fully closed state, the block 32 is slid back into the slot 33 by the elastic force of the spring 31, and is locked.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
