Description

Technical Field

[0001] This utility model relates to the field of sheet metal housing technology, specifically to a corrosion-resistant and rust-proof sheet metal housing. Background Technology

[0002] Sheet metal housings are widely used in electronic equipment, machinery, and many other fields, and their performance directly affects the stability and service life of the equipment. However, traditional sheet metal housings have many shortcomings in terms of corrosion and rust prevention. On the one hand, housings made of ordinary steel are prone to oxidation and rust when exposed to complex environments such as humidity and acids and alkalis for a long time, leading to a decrease in the structural strength of the housing and even damage, affecting the safety of internal components. On the other hand, existing anti-corrosion coatings are difficult to meet the requirements of long-term use in terms of durability and protective effect. Over time, the coating is prone to peeling and aging, leaving the metal substrate unprotected.

[0003] Meanwhile, dust, impurities, and other contaminants easily adhere to the surface of sheet metal housings. These contaminants not only affect the appearance of the housing but may also react chemically with the metal in humid environments, accelerating corrosion. Traditional housings lack effective dust prevention and cleaning mechanisms, allowing dust and impurities to enter the housing through gaps and accumulate on critical components, affecting normal equipment operation and even causing malfunctions. Furthermore, regular manual cleaning not only increases maintenance costs and workload but also makes it difficult to guarantee cleaning effectiveness. Therefore, a corrosion- and rust-resistant sheet metal housing is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a corrosion-resistant and rust-proof sheet metal housing. By reinforcing the housing material itself and treating the surface, the overall corrosion resistance of the housing is improved, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant and rust-proof sheet metal housing, comprising a housing body, wherein the housing body includes a corrosion-resistant inner core, a reinforcing plate, and a corrosion-resistant paint;

[0006] Two sets of sliding grooves are symmetrically opened through the surface of the shell body. Two sets of belts are rotatably installed inside the shell body corresponding to the sliding groove positions. A brush is glued to the outer arc surface of each set of belts. The brushes rotate and extend out from inside the sliding groove.

[0007] A positioning plate is installed outward from the surface of the belt via a groove, and a cleaning cotton is installed on the side of the positioning plate corresponding to the surface of the housing body.

[0008] Preferably, the surface of the anti-corrosion inner core is provided with several sets of grooves, and the reinforcing plate is provided with several sets of grooves corresponding to the grooves. The reinforcing plate is embedded and installed inside each set of grooves, and the surface of the anti-corrosion inner core is sprayed with anti-corrosion paint.

[0009] Preferably, a set of drive gears is installed inside the housing body at each end corresponding to the inside of the belt. The central shaft of the drive gears passes through the surface of the housing body, and an electric drive is installed on each of the two sets of drive gear central shafts.

[0010] Preferably, the drive gear is meshed with a first rotating rod on both the upper and lower sides, and a set of first rubber wheels are respectively installed at both ends of the first rotating rod. The first rotating rod is rotatably installed inside the housing body.

[0011] Preferably, several sets of driven gears are installed at equal intervals between the two sets of driving gears, and the central shaft of each set of driven gears is installed through the housing body. A set of positioning seats is installed on the outer surface of the housing body corresponding to the central shaft of each set of driven gears.

[0012] Preferably, the driven gear is meshed with two sets of second rotating rods, and second rubber wheels are respectively installed at both ends of the second rotating rods. The belt is sleeved on the outer arc surface of each set of first and second rubber wheels.

[0013] Preferably, the positioning plate is installed on the belt surface via a connecting rod, the outer arc surface of the positioning plate slides against the inner wall of the groove, and the cleaning cotton works against the surface of the housing body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This corrosion-resistant and rust-proof sheet metal housing boasts multiple significant advantages. In terms of corrosion and rust resistance, the corrosion-resistant inner core, made of hot-dip galvanized steel, isolates air and moisture through a zinc layer, combined with chlorinated rubber anti-corrosion paint, forming a double protection that effectively resists water, acid, alkali, and salt spray corrosion, making it suitable for harsh environments such as humid conditions and greatly extending the housing's service life. Regarding structural strength, the design of the grooves on the surface of the corrosion-resistant inner core and the reinforcing plate reinforces the inner core, enhancing the overall strength of the housing and increasing its resistance to mechanical impact. For cleaning, the sliding grooves on the housing surface, along with a belt and brush, not only prevent dust from entering the housing but also promptly clean impurities from the sliding grooves, ensuring smooth movement of the positioning plate. Simultaneously, the belt drives the cleaning cotton on the positioning plate to move against the housing surface, periodically cleaning the surface, reducing cleaning frequency, and delaying corrosion. The cooperation between the positioning plate and the sliding grooves ensures stable operation of the cleaning cotton. Furthermore, the transmission system, composed of a drive gear, driven gear, rotating rod, and rubber wheels, driven by an electric actuator, ensures stable belt rotation, guaranteeing reliable operation of the cleaning function.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a corrosion-resistant and rust-proof sheet metal housing, such as... Figures 1-7 As shown, it includes a housing body 1, which includes an anti-corrosion inner core 2, a reinforcing plate 3, and an anti-corrosion paint 4. The anti-corrosion inner core 2 and the anti-corrosion paint 4 are used to enhance the overall corrosion resistance of the housing, while the reinforcing plate 3 can improve the overall strength of the housing.

[0026] Two sets of sliding grooves 5 are symmetrically opened through the surface of the housing body 1. Two sets of belts 14 are rotatably installed inside the housing body 1 at the corresponding positions of the sliding grooves 5. A brush 15 is glued to the outer arc surface of each set of belts 14. The brush 15 rotates and extends out from inside the sliding groove 5. The two sets of sliding grooves 5 opened on the surface of the housing body 1 ensure the movement of the positioning plate 17. The brush 15 on the outer surface of the belt 14 can prevent dust from entering the interior of the housing body 1 during the rotation of the belt 14 and clean the impurities inside the sliding groove 5 in time, so as to avoid the problem of the positioning plate 17 not moving smoothly.

[0027] A positioning plate 17 is installed on the surface of the belt 14 outward through the slide groove 5. A cleaning cotton 16 is installed on the side of the positioning plate 17 corresponding to the surface of the housing body 1. The positioning plate 17 positions the cleaning cotton 16 so that the cleaning cotton 16 can move along the surface of the housing body 1 to better clean the surface of the housing body 1, thereby reducing the corrosion of the surface of the housing body 1.

[0028] Preferably, the surface of the anti-corrosion inner core 2 has several sets of grooves, and the reinforcing plate 3 has several sets of corresponding grooves. The reinforcing plate 3 is embedded in each set of grooves. The surface of the anti-corrosion inner core 2 is sprayed with anti-corrosion paint 4. The grooves inside the anti-corrosion inner core 2 limit the reinforcing plate 3, and the reinforcing plate 3 strengthens the anti-corrosion inner core 2. The anti-corrosion inner core 2 is made of hot-dip galvanized steel. By immersing the steel in molten zinc, a zinc layer is formed on its surface. The zinc layer can effectively isolate the steel from contact with air and moisture, providing good anti-corrosion performance. Hot-dip galvanized steel has high corrosion resistance and wear resistance, and can withstand certain mechanical impacts. In addition, the anti-corrosion paint 4 sprayed on the surface of the anti-corrosion inner core 2 is chlorinated rubber anti-corrosion paint, composed of chlorinated rubber, plasticizer, pigments, etc., and has good water resistance, acid and alkali resistance, and salt spray resistance. It can be applied at lower temperatures, and the coating after film formation is tough and wear-resistant, effectively preventing water, oxygen, and other media from penetrating into the shell, extending the service life of the shell, and is especially suitable for humid environments.

[0029] Preferably, a set of drive gears 6 are installed inside the housing body 1 at both ends corresponding to the inside of the belt 14. The central shaft of the drive gears 6 passes through the surface of the housing body 1, and an electric driver 7 is installed on the central shaft of each set of drive gears 6. The electric driver 7 is a UNIC-20, which is a miniature electric head torque motor driver with a voltage of 220V, a current of 0.4A, an output torque of 20kgf.m, an opening / closing time of 30 / 25sec, and a control angle of 0-90°. It has various models such as A. ordinary type, B. passive contact type, H. potentiometer type, and C. intelligent adjustment type. The electric driver 7 controls the rotation of the drive gears 6, thereby driving the first rotating rod 8 to rotate, so that the first rubber wheel 9 has enough force to drive the belt 14 to rotate.

[0030] Preferably, the drive gear 6 is meshed with a first rotating rod 8 on both the upper and lower sides. A set of first rubber wheels 9 are respectively installed at both ends of the first rotating rod 8. The first rotating rod 8 is rotatably installed inside the housing body 1. The first rotating rod 8 is rotatably connected to the housing body 1 to ensure the stable operation of the belt 14. The first rubber wheels 9 can increase the friction force and further improve the stability of the belt 14.

[0031] Preferably, several sets of driven gears 10 are installed at equal intervals between the two sets of driving gears 6. The central shaft of each set of driven gears 10 passes through the housing body 1. A set of positioning seats 11 is installed on the outer surface of the housing body 1 corresponding to the central shaft of each set of driven gears 10. The driven gears 10 work in conjunction with the two sets of driving gears 6, so that the belt 14 is supported in the middle, which can better improve its stability and better drive the cleaning cotton 16 to clean the surface of the housing body 1.

[0032] Preferably, the driven gear 10 is meshed with two sets of second rotating rods 12, one above the other. The two ends of the second rotating rods 12 are respectively equipped with second rubber wheels 13. The belt 14 is sleeved on the outer arc surface of each set of first rubber wheels 9 and second rubber wheels 13. The second rotating rods 12 and second rubber wheels 13 work on the same principle as the first rotating rods 8 and first rubber wheels 9 to assist the belt 14 in rotating and to support the belt 14, so as to prevent the positioning plate 17 from becoming loose during movement.

[0033] Preferably, the positioning plate 17 is installed on the surface of the belt 14 via the connecting rod. The outer arc surface of the positioning plate 17 slides against the inner wall of the slide groove 5. The cleaning cotton 16 works against the surface of the housing body 1. The slide groove 5 limits the connecting rod, allowing the cleaning cotton 16 to move against the surface of the housing body 1. Since the cleaning cotton 16 is not used frequently, the surface of the housing body 1 is only cleaned periodically, so that the cleaning cotton 16 can be replaced after a long period of use. This is mainly to reduce the number of times the surface of the housing body 1 is cleaned and to delay the corrosion of the surface of the housing body 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
