Description

TECHNICAL FIELD

[0001] The utility model relates to modern building field especially, and relates to a windproof electric rolling shutter door. BACKGROUND

[0002] In modern building, the application of electric rolling shutter door is extremely wide, and its figure can be often seen in commercial place, industrial plant or residential garage etc.

[0003] However, the traditional electric rolling shutter door exposes many defects when facing strong wind environment.When the strong wind acts on the door body, the large lateral force is produced, and the door body lacks sufficient constraint and stability mechanism in the guide rail due to the limitation of structural design.Under the influence of this lateral force, the door body is prone to sway, which not only causes large noise in the running process of the door body, affects the quietness and comfort of the surrounding environment, but also accelerates the wear of each part of the door body, shortens the service life of the rolling shutter door.Seriously, it can even make the door body separate from the guide rail, cause safety accident, and threaten the safety of personnel and property.

[0004] Therefore, a windproof electric rolling shutter door is proposed, which can effectively prevent the door body from swaying due to lateral force under the action of strong wind, and ensure the stable running of the door body in the guide rail. CONTENT OF THE UTILITY MODEL

[0005] The utility model discloses in view of the prior art's insufficient, through the cooperation of the windproof groove and curtain piece guide block.The windproof groove is trapezoidal, when the strong wind produces lateral force to the door body, the trapezoidal structure can make the curtain piece guide block receive an inward component force.The knurling treatment of the inner surface of the windproof groove increases the friction between the curtain piece guide block.This friction can further prevent the door body from swaying under the action of strong wind, so that the door body can work normally even in high wind speed environment, and will not appear running failure due to the interference of wind, ensuring that the electric rolling shutter body runs stably in the guide rail.

[0006] In order to solve the above technical problems, the utility model solves the problem that the device effectively prevents the door body from swaying due to lateral force under the action of strong wind, and ensures the stable running of the door body in the guide rail through the following technical scheme.

[0007] In order to realize the above purpose, the utility model adopts the following technical scheme:

[0008] A windproof electric rolling shutter door, comprising an electric rolling shutter body, the two sides of the electric rolling shutter body are provided with guide rails, the inside of the guide rail is provided with a windproof groove, the two sides of the curtain piece at the bottom of the electric rolling shutter body are symmetrically connected with curtain piece guide blocks, the curtain piece guide blocks are slidably connected in the inside of the windproof groove, the inner wall of the windproof groove is provided with knurling, and the knurling can cooperate with the curtain piece guide blocks.

[0009] Preferably, the bottom of the guide rail is provided with a detachable stable bottom plate for limiting.

[0010] Preferably, the stable bottom plate is threadedly connected with the bottom of the guide rail through a fastening bolt.

[0011] Preferably, a sealing convex layer is arranged between the guide rail and the stable bottom plate for sealing.

[0012] Preferably, one end of the sealing convex layer is glued to the outer periphery of the stable bottom plate, and the other end is in close contact with the outer periphery of the bottom of the guide rail, and the top of the guide rail is provided with a first preset screw hole.

[0013] Preferably, the bottom of the motorized roller body curtain is provided with a stable base, and the stable base is used to carry the motorized roller body in a pulled-down state, and the corner of the stable base is provided with a second preset screw hole, and the stable base is in the same horizontal line with the stable bottom plate and is in a flush state.

[0014] Preferably, a sealing structure is arranged between the stable base and the motorized roller body curtain for sealing treatment.

[0015] Preferably, an inner groove is formed in the middle of the top end of the stable base, one end of the sealing structure is inserted into the inner groove, and the other end extends to the front and rear ends of the inner groove.

[0016] Preferably, a stable groove is formed in the inner part of the sealing structure, and the bottom of the motorized roller body curtain is inserted into the stable groove.

[0017] Preferably, a guide opening is glued to the outer periphery of the opening of the stable groove for guiding the curtain of the motorized roller body.

[0018] Compared with the prior art, the utility model has the advantages of the following beneficial effects:

[0019] The anti-wind motorized roller door provided in the application is matched with the curtain guide block through the windproof groove. The windproof groove is trapezoidal, and when the strong wind generates a lateral force on the door body, the trapezoidal structure can make the curtain guide block receive an inward component force. The knurling treatment of the inner surface of the windproof groove increases the friction between the curtain guide block. The friction can further prevent the door body from shaking under the action of strong wind, so that the door body can normally work even in a high wind speed environment, and will not appear running failure due to the interference of wind, and the motorized roller body door body is ensured to run smoothly in the guide rail.

[0020] The stable bottom plate is connected with the bottom of the guide rail through a fastening bolt, and the stability of the guide rail is enhanced. The stable bottom plate provides a stable base for the guide rail, so that the guide rail can have better support when bearing the lateral force brought by strong wind, and deformation or displacement of the guide rail is prevented, thereby ensuring the smooth running of the door body in the guide rail.

[0021] The sealing convex layer is located between the guide rail and the stable base plate, and its rubber material can tightly fill the gap between the two during installation. In an environment with more wind and sand, this sealing design can effectively prevent wind and sand from entering the indoor environment through the bottom of the guide rail, keeping the indoor environment clean and reducing the impact of dust on indoor objects and personnel.

[0022] The sealing structure between the stable base and the curtain piece of the electric roller shutter body plays an important sealing role. When the door body is pulled down, the bottom of the curtain piece is inserted into the stable groove of the sealing structure, and the rubber material of the sealing structure can tightly fit the curtain piece to prevent wind and sand from entering from the bottom of the door body. Moreover, the guide opening around the opening of the sealing structure not only helps the curtain piece to be accurately inserted into the stable groove, but also blocks wind and sand to some extent. In dusty or windy weather, this sealing design can significantly reduce the amount of dust in the indoor environment and improve indoor air quality.

[0023] The close cooperation between the windproof groove and the curtain piece guide block and the stable structure design effectively reduce the shaking of the door body during operation. The reduction of door body shaking means that the friction and collision between the curtain piece and the guide rail and other components are reduced, thereby reducing the noise generated during operation. In commercial places, residential garages and other environments sensitive to noise, this low-noise operation of the roller shutter door can provide a quieter environment and will not disturb the surrounding personnel. The sealing structure and the sealing convex layer also play a certain role in reducing noise. They can prevent external wind and sand from entering the door body, avoid noise caused by increased friction between components due to the entry of wind and sand, and further ensure the quietness of the roller shutter door operation.

[0024] The stable base plate and the guide rail are connected by fastening bolts, which is a simple and reliable connection method that is easy to operate during installation. Moreover, the detachable design of the stable base plate facilitates the cleaning of the windproof groove inside the guide rail. For example, after the roller shutter door has been used for a period of time, if dust or debris accumulates in the windproof groove, the stable base plate can be easily removed for cleaning, ensuring the normal operation of the door body.

[0025] The detachable stable base plate and the easily replaceable sealing structure mentioned above reflect the advantages of the roller shutter door in maintenance. If the sealing structure is worn or damaged after long-term use, due to its design of being inserted into the inner groove of the stable base at one end and extending to the front and rear ends of the inner groove at the other end, it can be easily replaced without the need for large-scale disassembly and reinstallation of the entire door structure, reducing maintenance costs and difficulty.

Embodiment

[0041] Please refer to Figures 1-9 A wind-resistant electric roller shutter door, comprising an electric roller shutter body 1, guide rails 2 are arranged on both sides of the electric roller shutter body 1, a windproof groove 201 is formed in the inside of the guide rail 2, curtain guide blocks 101 are symmetrically connected to both sides of the bottom curtain of the roller shutter body 1, the curtain guide blocks 101 are slidingly connected to the inside of the windproof groove 201, and knurls are arranged on the inner wall of the windproof groove 201 and can cooperate with the curtain guide blocks 101.

[0042] The wind-resistant electric roller shutter door of the present application is mainly composed of an electric roller shutter body 1, curtain guide blocks 101, guide rails 2, a windproof groove 201, a stable bottom plate 3, a stable base 4 and a sealing structure 5, and the following is a detailed structure and working principle.

[0043] (I) Material selection

[0044] Curtain guide blocks 101

[0045] Wear-resistant nylon or polyurethane materials are adopted. These materials have certain elasticity and self-lubricating properties, which can reduce wear and tear during long-term contact and sliding with the windproof groove 201, and ensure smooth operation of the door body.

[0046] Sealing convex layer 302 and sealing structure 5

[0047] The sealing convex layer 302 is made of rubber. Rubber has good flexibility and sealing performance, which can tightly fill the gap between the guide rail 2 and the stable bottom plate 3, preventing wind and dust from entering.

[0048] The sealing structure 5 is also made of rubber. The stable groove 502 inside is used to accommodate the bottom of the curtain piece of the electric roller shutter body 1, and the guide opening 501 around the opening of the stable groove 502 is made of hard material such as plastic or metal to ensure effective guidance of the curtain piece.

[0049] The stable bottom plate 3 and the stable base 4

[0050] The stable bottom plate 3 and the stable base 4 can be made of metal materials such as aluminum alloy or stainless steel. These metal materials have sufficient strength and stability to withstand the weight of the door body and the lateral force generated by strong wind.

[0051] (2) Installation steps

[0052] Installation of guide rail 2 and windproof groove 201

[0053] First, install the guide rail 2 on both sides of the door frame. The installation position of the guide rail 2 should be ensured to be vertical and parallel, which can be fixed by using bolts through the first preset screw hole 202 pre-drilled on the door frame.

[0054] After the installation of the guide rail 2, the windproof groove 201 inside it is in the working position. The windproof groove 201 is trapezoidal in shape, which helps to keep the door body stable under strong wind.

[0055] Installation of curtain piece guide block 101

[0056] Install the curtain piece guide block 101 on the edge of the bottom curtain piece of the electric roller shutter body 1. Since the curtain piece guide block 101 is made of wear-resistant nylon or polyurethane material, it should be firmly fixed on the curtain piece during installation, which can be achieved by using glue or buckle connection.

[0057] Installation of stable bottom plate 3

[0058] The stable bottom plate 3 is connected with the bottom of the guide rail 2 through the fastening bolt 301. During the connection process, the sealing convex layer 302 made of rubber around the stable bottom plate 3 should be in close contact with the outer groove of the guide rail 2 to achieve good sealing effect.

[0059] Installation of stable base 4

[0060] The stable base 4 needs to be pre-buried in the ground inside the door bottom during installation. During ground construction, the installation position is reserved according to the size and shape of the stable base 4, and the stable base 4 is placed and fixed at the predetermined position. The second preset screw hole 402 opened at the corner of the stable base 4 can be connected with the ground embedded part by using a bolt.

[0061] Sealing structure 5 installation

[0062] The sealing structure 5 is installed between the bottom of the electric roller shutter body 1 and the stable base 4. One end of the sealing structure 5 is inserted into the inner groove 401 opened in the middle of the top end of the stable base 4, and the other end extends to the front and rear ends of the inner groove 401 and is laid on the surface of the stable base 4. The stable groove 502 inside the sealing structure 5 is used to accommodate the bottom of the curtain piece of the electric roller shutter body 1, and the guide port 501 glued around the opening of the stable groove 502 is used to guide the curtain piece to insert into the stable groove 502.

[0063] II. Working principle

[0064] (1) The principle of the electric roller shutter body 1

[0065] The motor in the roller shutter box at the top of the electric roller shutter body 1 is connected with the curtain piece through a transmission device such as gear, chain or screw. When the motor starts, the rotary motion of the motor is converted into the linear motion of the curtain piece through the transmission device, realizing the opening and closing operation of the door body. For example, when the gear transmission is used, the gear on the motor shaft is engaged with the gear connected with the curtain piece, and the rotation of the motor drives the engaged gear to rotate, thereby making the curtain piece rise or fall. In this process, the parameters such as modulus, tooth number and tooth shape of the gear need to be accurately designed to ensure the stability and reliability of the transmission.

[0066] The guiding and supporting effect of the guide rail 2

[0067] The guide rail 2 provides accurate guidance for the up and down movement of the door body. During the lifting process of the door body, the two sides of the electric roller shutter body 1 move along the guide rail 2, and the shape and size accuracy of the guide rail 2 ensure the linear motion of the door body in the vertical direction. At the same time, the guide rail 2 bears part of the weight of the door body, especially when the door body is lowered, the guide rail 2 disperses the weight of the door body to the door frame through the contact with the door body, ensuring that the door body will not deviate or deform during operation due to the action of gravity.

[0068] (2) Windproof principle

[0069] The windproof groove 201 is designed in a trapezoidal shape, and its mechanical principle is based on force decomposition. When strong wind acts on the door body to generate a lateral force, the trapezoidal wall surface of the windproof groove 201 exerts a force on the curtain piece guide block 101 in the opposite direction of the lateral force. By reasonably designing the angle of the windproof groove 201, the lateral force generated by the strong wind can be effectively counteracted, ensuring the stability of the door body.

[0070] The knurling treatment on the inner surface of the windproof groove 201 increases the surface roughness. The knurling treatment increases the coefficient of friction, and when the curtain guide block 101 slides in the windproof groove 201, even under strong winds, the increased friction can better prevent the door from swaying and shifting.

[0071] The function of stabilizing the base plate 3 and the sealing protrusion 302

[0072] The stabilizing base plate 3 is connected to the bottom of the guide rail 2 via fastening bolts 301, forming a stable support structure. Under strong winds, the stabilizing base plate 3 can withstand the lateral forces and bending moments transmitted by the guide rail 2. From a mechanical point of view, the stabilizing base plate 3 is equivalent to an extended base for the guide rail 2, increasing the stress-bearing area at the bottom of the guide rail 2 and reducing the pressure per unit area on the ground, thereby ensuring the stability of the guide rail 2 under strong winds.

[0073] Sealing and protection of sealing protrusion 302:

[0074] The sealing protrusion 302 plays a crucial role in preventing windblown sand and dust from entering the room. When windblown sand attempts to enter through the bottom of the guide rail 2, the rubber material of the sealing protrusion 302, when compressed, fills the gap between the guide rail 2 and the stable base plate 3. Its sealing principle is based on the elastic deformation of rubber, which can adapt to different gap shapes and sizes, forming an effective barrier to block external windblown sand and dust.

[0075] The functions of the stabilizing base 4 and the sealing structure 5

[0076] The stabilizing base 4 is embedded in the ground at the bottom of the door. When the electric roller shutter body 1 is pulled down, the stabilizing base 4 acts as a load-bearing platform for the door, supporting its weight. From a structural mechanics perspective, the stabilizing base 4 and the ground form a stable support system, ensuring the stability of the door when it is lowered. At the same time, the stabilizing base 4 and the stabilizing base plate 3 are on the same horizontal line, ensuring the vertical alignment of the door and preventing it from tilting due to uneven force.

[0077] Sealing and auxiliary stabilization of sealing structure 5:

[0078] When the door is pulled down, the sealing structure 5, through its internal stabilizing groove 502, accommodates the bottom of the electric roller shutter body 1 slats, achieving a seal at the bottom of the door. Its sealing principle is similar to that of the sealing protrusion 302, based on the elastic deformation of rubber to fill gaps. Simultaneously, the guide opening 501 on the outer periphery of the sealing structure 5 not only guides the slats into the stabilizing groove 502 but also restricts the lateral movement of the slats to a certain extent, further enhancing the stability of the door at the bottom. The inner groove 401 at the top of the stabilizing base 4, in conjunction with one end of the sealing structure 5, further ensures the stable installation of the sealing structure 5 and facilitates the replacement of worn parts during long-term use.

[0079] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
