Furthermore, when an element is considered to be "transmission-connected" to another element, it is sufficient that the two can achieve power transmission, and its specific implementation method can be implemented using existing technologies and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0032] Please refer to the attached Figure 1 -Attached Figure 9, an embodiment of the present invention proposes a rainproof elevator, which includes a chassis surrounded and fixed by an upper cover plate 1, a lower cover plate 2, a left side plate 3, a right side plate 4, a front panel 5 and a rear panel 6, and a vertical U-shaped water guide groove 7 is fixedly installed at the four corners inside the chassis. The notches of the four U-shaped water guide grooves 7 correspond one by one to the splicing gap formed between the front panel 5 and the left side plate 3, the right side plate 4, and the splicing gap formed between the rear panel 6 and the left side plate 3, the right side plate 4. A plurality of drainage holes 8 are provided on the lower cover plate 2.

[0033] Specifically, if Figure 7 As shown, the top of the U-shaped water guide trough 7 is provided with an upper flange, and the upper flange is provided with a mounting hole for cooperating with the screw 13 to be fixedly connected to the upper cover 1. The bottom of the U-shaped water guide trough 7 is provided with a lower flange, and the lower flange is provided with a mounting hole for cooperating with the screw 13 to be fixedly connected to the lower cover 2, thereby realizing the fixed installation of the U-shaped water guide trough 7.

[0034] It can be understood that the chassis is surrounded by an upper cover 1, a lower cover 2, a left side panel 3, a right side panel 4, a front panel 5 and a rear panel 6, and is fixed by screws 13 to form a closed space to protect the internal components from the external environment.

[0035] The utility model fixes an upright U-shaped water guide groove 7 at the four corners inside the chassis, and the notches of the four U-shaped water guide grooves 7 correspond one by one to the splicing gaps formed between the front panel 5 and the left side panel 3 and the right side panel 4, and the splicing gaps formed between the rear panel 6 and the left side panel 3 and the right side panel 4, that is, the notches of the four U-shaped water guide grooves 7 correspond one by one to the four splicing gaps. When rainwater seeps into the interior of the chassis along the four splicing gaps, the water will flow to the lower cover plate 2 under the guidance of the U-shaped water guide grooves 7 and be discharged through the drainage holes 8, thereby preventing rainwater from contacting the electrical components inside the chassis and accumulating inside the chassis, thereby protecting the electrical components inside the chassis from water damage, improving the stability and service life of the equipment, ensuring that the elevator can achieve rainproof effect even on rainy days outdoors, and reducing maintenance costs.

[0036] In this embodiment, the front and rear edges of the upper cover 1 and the lower cover 2 are respectively provided with extension edges 9 extending vertically toward the interior of the chassis, and a number of connection holes 10 are provided on the extension edges 9. The left side panel 3 and the right side panel 4 are U-shaped panels consisting of a straight panel 11 and vertical folding panels 12 on both sides, and the folding panels 12 are provided with connection holes 10. The folding panels 12 are fitted with the corresponding extension edges 9 and fixed with the connection holes 10 by screws 13. The front panel 5 and the rear panel 6 are also provided with connection holes 10. The front panel 5 and the rear panel 6 are respectively fitted with the corresponding extension edges 9 and fixed with the connection holes 10 by screws 13. The left and right side edges of the front panel 5 and the rear panel 6 are respectively fitted with the corresponding edges of the folding panels 12 and spliced.

[0037] Specifically, two connecting holes 10 are respectively provided at the left and right ends of the extended edge 9, and a connecting hole 10 is respectively provided at the upper and lower ends of the folding plate 12. A connecting hole 10 is installed at each of the four corners of the front panel 5 and the rear panel 6. After the upper cover plate 1, the lower cover plate 2, the left panel 3, the right panel 4, the front panel 5, and the rear panel 6 are assembled, the sixteen connecting holes 10 of the four extended edges 9 correspond one by one to the sixteen connecting holes 10 of the front panel 5, the rear panel 6 and the four folding plates 12, and then are fixed by screws 13.

[0038] In a preferred solution of this embodiment, the left and right edges of the front panel 5 and the rear panel 6 and the edge of the folding plate 12 are respectively provided with folded edges 14 extending vertically toward the interior of the chassis.

[0039] It can be understood that the utility model has folded edges 14 extending vertically toward the interior of the chassis through the left and right edges of the front panel 5 and the rear panel 6 and the edge of the folding plate 12. When the chassis is installed, the folded edges 14 of the front panel 5 and the rear panel 6 are respectively fitted with the folded edges 14 of the corresponding folding plates 12. The gaps formed in this way are better able to prevent rainwater from seeping in, and at the same time, the rainwater seeping in from the gaps can be better guided into the spatial range of the U-shaped water guide trough 7.

[0040] In a preferred solution of this embodiment, the chassis further includes a rainproof outer cover 15 , which covers the upper cover 1 and has a surrounding plate 16 extending downwardly around the rainproof outer cover 15 .

[0041] It can be understood that the utility model covers the upper cover plate 1 through the rainproof outer cover 15 and extends downward to form the enclosure 16. The rainproof outer cover 15 can wrap the connection interface between the upper cover plate 1 and the left panel 3, the right panel 4, the front panel 5, and the rear panel 6, thereby improving the rainproof effect of the chassis.

[0042] In this embodiment, the elevator also includes a supporting mechanism, a lifting drive mechanism and a retractable wire mechanism installed inside the chassis; the supporting mechanism is used to install the lifting drive mechanism and the retractable wire mechanism, and the lifting drive mechanism is used to control the operation of the retractable wire mechanism; the retractable wire mechanism includes a wire reel 17, which is rotatably installed on the supporting mechanism by rotating the main shaft 18, and a wire rope 19 is wound on the wire reel 17, and a wire hole 20 is provided on the lower cover 2, and one end of the wire rope 19 passes through the wire hole 20 of the lower cover 2 and is used to connect with external equipment, such as an LED lamp.

[0043] Specifically, the winding drum 17 includes two upper and lower disks, and the wire rope 19 is superimposed and wound in the winding space formed by the upper and lower disks.

[0044] It is understandable that the support mechanism is responsible for fixing and supporting the lifting drive mechanism and the retractable wire mechanism so that the lifting drive mechanism and the retractable wire mechanism can operate smoothly. The lifting drive mechanism is responsible for controlling the operation of the retractable wire mechanism to achieve the retractable action of the rope 19.

[0045] In this embodiment, if Figure 4 、 Figure 5 、 Figure 6 As shown, the supporting mechanism includes a main bridge plate 21 which is parallel to the front panel 5 and the rear panel 6 and fixedly connected to the upper cover plate 1 and the lower cover plate 2 respectively, and several groups of wire protection plates 22 installed on the main bridge plate 21 and arranged around the winding reel 17, and the rotating main shaft 18 is rotatably mounted on the main bridge plate 21.

[0046] Specifically, the top of the main bridge plate 21 is fixedly connected to the upper cover plate 1 by screws 13, and the bottom of the main bridge plate 21 is fixedly connected to the lower cover plate 2 by screws 13. The main bridge plate 21 not only provides physical support but also acts as a spatial separator. Its top and bottom ends are fixedly connected to the upper cover plate 1 and the lower cover plate 2, respectively, which also enhances the structural stability of the entire chassis. The wire guard plate 22 is mainly used to prevent the wire rope 19 from being exposed and jamming the wires when the chassis is tilted during transportation, causing machine malfunction.

[0047] In this embodiment, if Figure 5 、 Figure 6As shown, the support mechanism also includes a first reinforcing connecting plate 23 and a second reinforcing connecting plate 24 located on the left and right sides of the interior of the chassis and fixedly connected to the upper cover 1 and the lower cover 2 respectively. A display screen 25 is installed on the first reinforcing connecting plate 23, and a transparent touch screen protection plate 26 is provided on the surface of the display screen 25. An opening is provided on the chassis for accommodating the transparent touch screen protection plate 26, and the gap between the transparent touch screen protection plate 26 and the chassis opening is sealed with a waterproof adhesive coating.

[0048] It is understood that the provision of the first reinforcing connecting plate 23 and the second reinforcing connecting plate 24 can enhance the structural stability of the chassis. Furthermore, folded edges can be provided on the first reinforcing connecting plate 23 and the second reinforcing connecting plate 24 to enhance the structural rigidity of the first reinforcing connecting plate 23 and the second reinforcing connecting plate 24. The touch screen display 25 is used to provide a human-machine interface for setting parameters of the elevator. The transparent touch screen protection plate 26 is a protective component designed specifically for touch screen devices. Users can perform touch operations as if they were directly operating the screen, without affecting the user experience. By sealing the gap between the transparent touch screen protection plate 26 and the chassis opening with a waterproof adhesive coating, moisture, dust, and other foreign matter are effectively prevented from invading the interior of the chassis, protecting the internal electronic components.

[0049] In this embodiment, the lifting drive mechanism includes a motor 27, a power supply module 28 and a lifting control main board 29 installed on the main bridge plate 21. The power supply module 28 is electrically connected to the lifting control main board 29, and the motor 27 is electrically connected to the lifting control main board 29. The output shaft of the motor 27 is connected to the rotating main shaft 18 through a transmission assembly to drive the rotating main shaft 18 to rotate.

[0050] Specifically, the power supply module 28 is responsible for providing stable power to the lift control mainboard 29, motor 27, and other electrical components, ensuring their proper function. The lift control mainboard 29 is responsible for receiving operational instructions, processing data, and sending control signals to the motor 27, precisely controlling the start, stop, and speed adjustment of the motor 27 to ensure smooth operation of the elevator. The transmission assembly can be implemented using a gear transmission module, which includes gears and a drive belt (not shown). Through the coordination of the gears and the drive belt, the output shaft of the motor 27 drives the rotation of the rotating main shaft 18.

[0051] In a preferred solution of this embodiment, an air vent 30 is provided on the lower cover plate 2 , and a waterproof fan 31 is installed above the air vent 30 at the bottom of the chassis.

[0052] It is understandable that the running of the waterproof fan 31 is used to draw air to keep the inside of the chassis dry, and is also used to enhance the heat dissipation effect inside the chassis.

[0053] In this embodiment, waterproof rubber rings 32 are provided between all exposed screws 13 on the outer surface of the chassis and the outer surface of the chassis, which effectively prevent rainwater from penetrating into the interior of the chassis through the gaps in the screws 13. The outer surface of the chassis is sprayed with a waterproof paint coating, and the surface of the electronic components inside the chassis is coated with a waterproof and moisture-proof coating to form a protective film. Even in a high-humidity environment, it can effectively isolate moisture, avoid short circuits, corrosion and other problems, and ensure the normal operation of electronic components. A waterproof cable connector 33 and a safety ring 34 are installed on the top of the chassis.

[0054] Preferably, the exposed screws 13 are rust-proof screws 13, which further enhance the corrosion resistance of the device and extend its service life. The waterproof cable connector 33 is preferably a stainless steel waterproof cable connector 33, which is installed on the top of the chassis and uses a sealing rubber ring and nut to screw together with the electrical cable signal line to ensure a waterproof seal at the cable connection and prevent moisture from invading the interior of the chassis along the cable.

[0055] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which are protected by the present invention.
