DETAILED DESCRIPTION

[0038] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0039] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Example 1:

[0041] A voltage feedback monitor, such as Figure 1-8 As shown, it includes a box body 1, a box cover 5 movably hinged to one side of the box body 1, a lifting plate 2 connected to the inside of the box body 1 through a lifting part 4, and a monitor body 3 fixed to the top of the lifting plate 2. The lifting plate 2 is movably connected to the box body 1 through a telescopic guide rod 8.

[0042] The lifting part 4 includes a telescopic transmission component 9, a speed increasing component 11 and a driving component 13. The telescopic transmission component 9 and the speed increasing component 11 are coupled through a twisted rope 10, and the driving component 13 and the speed increasing component 11 are coupled through a twisted rope 2 12.

[0043] The lifting plate 2 is composed of a lifting plate 14 and two expansion plates 16 slidably connected to both sides of the lifting plate 14 through guide rods 15, and a spring 17 is buckled between the two guide rods 15.

[0044] The telescopic transmission assembly 9 includes a guide shell 20 fixed to the inner wall of the box body 1 and a "T"-shaped slide bar 18 fixed to the bottom of the lifting plate 14 by bolts. The "T"-shaped slide bar 18 is slidably connected to the inner side of the guide shell 20, and a spring 2 19 is buckled between the "T"-shaped slide bar 18 and the guide shell 20. The outer wall of the "T"-shaped slide bar 18 is movably equipped with a lifting block 21, and the two ends of the lifting block 21 are movably connected to the bottom of the two expansion plates 16 through connecting rods 22.

[0045] The spring rate of the second spring 19 is greater than that of the first spring 17 .

[0046] The monitor body 3 is composed of three monitoring units, and the three monitoring units are respectively fixed to the outer walls of the lifting plate 14 and the two expansion plates 16. The monitoring units are simply divided into three groups of internal electrical components based on the overall monitor body 3, and are respectively fixed using three outer shells. The three monitoring units are powered and connected by integrated wiring harnesses. The above descriptions are all well-known technologies to those skilled in the art and will not be elaborated in this embodiment.

[0047] When the device is in use, the box cover 5 can be opened, and the lifting plate 2 can be pushed out as a whole by using the lifting part 4. The two expansion plates 16 are then displaced to both sides. Then, the three monitoring units can be used to perform monitoring operations. After use, the two expansion plates 16 are retracted, and then the lifting plate 2 is lowered to the inside of the box body 1, and then the box cover 5 can be closed.

[0048] This device, by providing a box body 1 and a box cover 5, can provide wrapping protection for the monitor body 3, thereby increasing the safety of carrying. In addition, on this basis, the lifting plate 2 can also drive the monitor body 3 to rise and fall, which can increase the operating space when connecting the wire harness and connectors, and at the same time, the monitor body 3 is set to be composed of three monitoring units, and the lifting plate 2 is set to be a combination of a lifting plate 14 and an expansion plate 16, which can also be expanded horizontally to further increase the operating space and increase the convenience of use.

[0049] In order to solve the lifting control problem; Figure 4-7 As shown, the speed increasing assembly 11 includes a support plate 25 fixed to the inside of the housing 1, a gear ring 23 rotatably connected to the inner side of the support plate 25, a planetary gear 24 meshed with the inner side of the gear ring 23, and a sun gear 26 meshed with the inner side of the planetary gear 24, and a torsion spring is arranged between the gear ring 23 and the support plate 25.

[0050] The planetary gear 24 is rotatably connected to the inner wall of the support plate 25 via a rotating shaft, a reel 27 is fixed to the inner wall of the sun gear 26, the twisted rope 10 is wound around the outer wall of the reel 27, and the movable end of the twisted rope 10 is fixed to the bottom outer wall of the lifting block 21.

[0051] The driving assembly 13 includes a drum 28 and a hinge shaft 29. The hinge shaft 29 is fixed to the inner wall of the box cover 5 and is rotatably connected to the inner wall of the box body 1. The drum 28 is welded to the outer wall of the hinge shaft 29, and one end of the rope 12 is wound around the outer wall of the drum 28, and the other end of the rope 12 is wound around the outer wall of the gear ring 23.

[0052] When the box cover 5 is relatively opened, the hinge shaft 1 29 and the reel 28 rotate relative to each other, thereby driving the gear ring 23 to rotate through the twisted rope 2 12, thereby driving the sun gear 26 to rotate through the planetary gear 24, thereby driving the reel 27 to rotate, so that the gear ring 23 unwinds the twisted rope 10. At this time, since the spring coefficient of the spring 2 19 is greater than that of the spring 1 17, the spring 2 19 will rebound first, causing the "T"-shaped slide bar 18 to rise, thereby driving the lifting plate 14 and the expansion plate 16 to rise synchronously, until the lifting plate 14 and the expansion plate 16 slide out of the interior of the box body 1, the "T"-shaped slide bar 18 slides to the travel limit. At this time, the box cover 5 has not been fully opened. Continue to open it, so that the rope 10 will continue to unwind, and the spring 17 will rebound, causing the expansion plate 16 to open to both sides until the box cover 5 is fully opened and the expansion plate 16 is fully expanded. After use, the box cover 5 rotates in the opposite direction, so that the rope 10 is reeled, thereby pulling the lifting block 21 downward. Since the spring coefficient of spring 2 19 is greater than that of spring 17, spring 17 will first contract at this time until the expansion plate 16 is fitted with the lifting plate 14. The rope 10 continues to reel, so that the lifting plate 14 and the expansion plate 16 descend as a whole until the box cover 5 is fully closed and the lifting plate 14 and the expansion plate 16 are completely retracted.

[0053] This device, by setting up a telescopic transmission component 9, cleverly utilizes the progress coefficient relationship between spring 17 and spring 2 19, and combines the connection relationship between the components, thereby realizing the integration of the lifting drive of the lifting plate 14 and the expansion plate 16, and the expansion drive of the expansion plate 16 relative to the lifting plate 14, and can also ensure the movement sequence of the two when integrated, thereby reducing the power source setting and increasing the compactness of the structure.

[0054] In addition, the device is provided with a driving component 13, which uses the rotation and opening of the box cover 5 as power to control the lifting and lowering of the lifting plate 14 and the expansion plate 16, and the opening and closing of the expansion plate 16 relative to the lifting plate 14, thereby saving the arrangement of other power sources and increasing the synchronous linkage of the device, simplifying the operating steps and improving efficiency.

[0055] On the basis of the above, this device sets up a speed-increasing component 11 and utilizes the speed-changing relationship among the gear ring 23, the planetary gear 24, and the support plate 25 to multiply the small rotation angle change when the box cover 5 is opened and closed to the rotational movement of the scroll 27, thereby realizing the lifting stroke of the lifting plate 14 and the extension plate 16, and the extension stroke of the extension plate 16 relative to the lifting plate 14, further increasing the convenience of subsequent operations.

[0056] A handle 6 is provided on one side of the box body 1 , and the handle 6 and the box body 1 can be fixedly connected or rotatably connected.

[0057] 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 core that cooperates with the locking block 7 .

[0058] When the present embodiment is in use, the lock is firstly contacted and locked by the lock block 7, and then the box cover 5 is rotated to open it, and the hinge shaft 1 29 and the reel 28 rotate relative to each other, thereby driving the gear ring 23 to rotate through the twisted rope 2 12, thereby driving the sun gear 26 to rotate through the planetary gear 24, thereby driving the reel 27 to rotate, so that the gear ring 23 unwinds the twisted rope 10. At this time, since the spring coefficient of the spring 2 19 is greater than that of the spring 1 17, the spring 2 19 will rebound first, causing the "T"-shaped slide bar 18 to rise, thereby driving the lifting plate 14 and the expansion plate 16 to rise synchronously, until the lifting plate 14 and the expansion plate 16 slide out from the interior of the box body 1, and the "T"-shaped slide bar 18 slides to the travel limit. At this time, the box cover 5 has not been fully opened, and then Continue to open it, so that the rope 10 will continue to unwind, and the spring 17 will rebound, so that the expansion plate 16 will open to both sides until the box cover 5 is fully opened and the expansion plate 16 is fully expanded. After use, the box cover 5 rotates in the opposite direction, so that the rope 10 is reeled, thereby pulling the lifting block 21 downward. Since the spring coefficient of spring 2 19 is greater than that of spring 17, spring 17 will first shrink at this time until the expansion plate 16 is fitted with the lifting plate 14. The rope 10 continues to reel, so that the lifting plate 14 and the expansion plate 16 descend as a whole until the box cover 5 is fully closed and the lifting plate 14 and the expansion plate 16 are completely retracted. Then they are locked by the lock block 7 and the lock core, and can be carried by the handle 6.

[0059] Example 2:

[0060] A voltage feedback monitor, such as Figure 8As shown, in order to solve the position locking problem, this embodiment makes the following improvements on the basis of embodiment 1: a hinge shaft 2 30 is fixed on the top of the box body 1, the box cover 5 is rotatably connected to the outer wall of the hinge shaft 2 30, and the inner wall of the box cover 5 is slidably connected with two groups of blocks 32, the blocks 32 are connected to the hinge shaft 2 30 through springs 31, a card slot 33 is opened on the inner wall of the box cover 5, a card rod 34 is slidably inserted into the inner wall of the card slot 33, and a button 35 is fixed to the outer wall of the top of the card rod 34 by bolts.

[0061] When the present embodiment is in use, when the box cover 5 is opened from the closed state or closed from the open state, the button 35 can be pressed, so that the card slot 33 squeezes the card block 32, and the card block 32 is stored inside the hinge shaft 2 30, so that the box cover 5 can rotate relative to the box body 1. After rotating to the fully open state or the fully closed state, the card block 32 is subjected to the elastic force of the spring 31 and slides into the inside of the card slot 33 to achieve locking.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
