Description

Technical Field

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. The doors rotate up and down around the scroll above the door in a fixed slide. Rolling shutter doors are commonly used in shops, supermarkets, shopping malls, banks and other occasions.

[0003] Among them, in the prior art, the rolling shutter door dedicated to the silver pavilion uses a steel plate as the door sheet, and its two ends are connected with a chain to realize the rolling of the rolling shutter door. However, in order to increase the strength, it is necessary to set a reinforcing mechanism inside the door sheet and use reinforcing ribs for reinforcement. However, this structure has the following shortcomings: the overall weight is relatively heavy, the requirements for the motor are relatively high, and at the same time, the internal situation of the silver pavilion cannot be seen from the outside.

[0004] In order to solve this problem, in the prior art, multiple horizontal bars are arranged at intervals, and the two ends of the horizontal bars are connected to the chain. In order to increase the strength, a connecting piece is set between adjacent horizontal bars to connect the adjacent horizontal bars. The connecting piece needs to be rotatably connected to the horizontal bar. In order to prevent the connecting piece from moving horizontally, it is necessary to limit the lateral movement of the connecting piece so that its position is fixed. Figure 1 The structure of the connection between the connector 101 and the horizontal bar 102 is described above. A notch 103 is opened on the horizontal bar 102, and the connector 101 is inserted into the notch. A hole 104 is set at the end of the connector 101, and installation grooves 105 are set on both sides of the notch (the installation grooves are respectively located on the top and bottom surfaces of the horizontal bar. The figure shows that when the notches at the top and bottom of the connector are installed, the bottom of the installation groove is connected to the bottom of the horizontal bar). A coupling 106 is inserted into the hole, and the two ends of the coupling are inserted into the installation grooves on both sides of the notch. Subsequently, the bottom of the installation groove is welded to form a weld 107 to block it so that the coupling will not fall out of the notch.

DETAILED DESCRIPTION

[0044] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0045] Example 1: See Figures 2 to 9 As shown, a rolling shutter door body for silver pavilions includes a main body 1, wherein the main body 1 includes a plurality of chain plates 12 and a plurality of round steels 13, wherein the plurality of round steels 13 are arranged at intervals from top to bottom, and there is a vertical spacing between adjacent round steels 13, and a roller 14 is rotatably installed at both ends of each round steel 3;

[0046] A plurality of chain plates 12 are arranged at intervals in each vertical spacing, and the chain plates 12 are arranged perpendicular to the round steel bars 13. A through hole 15 is provided at each end of the chain plate 12, and the two ends of the chain plate 12 are rotatably connected to two adjacent round steel bars 13 through the through hole 15.

[0047] A flat iron 16 is also provided in each of the vertical intervals. The flat iron 16 is arranged parallel to the round steel 13 , and the flat iron 16 is fixedly connected to the middle parts of all the chain plates 16 in the corresponding vertical intervals.

[0049] In the utility model, a winding mechanism is provided at the top of the door body, and the door body is driven to be wound and released by the winding mechanism. In order to ensure the strength of the round steel and connect the round steel, the adjacent round steels are connected by chain plates, and the chain plates and the round steels are rotatably connected, so as not to affect the winding of the door body. At the same time, in order to limit the chain plates and prevent the chain plates from moving along the axial direction of the round steel, and in order to increase the overall strength of the door body, flat irons are arranged in each vertical spacing, and all the chain plates in the corresponding vertical spacing are connected by the flat irons, so that all the chain plates can be axially fixed to prevent the chain plates from moving, and the strength of the chain plates can be increased, and at the same time, the overall strength of the door panels can be increased. At the same time, multiple chain plates arranged at intervals can connect and support the round steels to prevent the round steels from being deformed due to the excessive width of the door, so as to ensure the strength and quality of the round steels. The chain plate is made of a steel plate with a thickness of at least 10 mm, the diameter of the round steel is greater than or equal to 14 mm, and the thickness of the flat iron is greater than or equal to 4 mm, so that the overall strength of the door body can be guaranteed. In addition, the door body is a hollow structure. After the door body is closed, the silver pavilion can see the outside of the silver pavilion from the inside, and the inside of the silver pavilion can also be seen from the outside of the silver pavilion (normally, other doors will be set up in the silver pavilion, and the rolling door is the outermost protective structure).

[0050] See also Figure 4 , 5 As shown, the middle of the flat iron 16 is provided with a plurality of through grooves 17 at intervals, and the middle of each chain plate 12 is inserted into one of the through grooves 17, and the chain plate 12 is welded and connected to the through grooves 17. Through the through grooves, the chain plate is directly inserted into the bar-shaped through grooves of the flat iron, and then the connection between the two is welded, which can increase the contact area between the flat iron and the chain plate, ensure the connection strength between the two, and at the same time, it will not take up more space and reduce the thickness of the rolling door. Among them, the welding place will have a weld 18.

[0051] See also Figure 2 , 3 As shown, the vertical spacing includes multiple groups of first vertical spacings 19 and second vertical spacings 110 alternately distributed from bottom to top, the chain plates 12 arranged in the first vertical spacings 19 include multiple double chain plates 111 and single chain plates 112 alternately distributed from left to right, and the chain plates 12 arranged in the second vertical spacings 110 include multiple single chain plates 112 and double chain plates 111 alternately distributed from left to right; wherein, the vertical spacings from bottom to top include the first vertical spacing, the second vertical spacing, the first vertical spacing, the second vertical spacing, etc., and are alternately distributed like this.

[0052] The double chain plate 111 includes two chain plates 12 spaced apart from each other, and a transverse spacing 113 is provided between the two chain plates 12;

[0053] The single chain plate 112 includes one chain plate 12 .

[0054] Each single chain plate 112 in the first vertical spacing 19 is disposed opposite to each double chain plate 111 in the second vertical spacing 110, and each single chain plate 112 in the second vertical spacing 110 is disposed opposite to each double chain plate 111 in the first vertical spacing 19;

[0055] Each single chain plate 112 within the first vertical spacing 19 is disposed within the lateral spacing 113 of each double chain plate 111 within the second vertical spacing 110;

[0056] Each single chain plate 112 within the second vertical spacing 110 is disposed within the lateral spacing 113 of each double chain plate 111 within the first vertical spacing 19 .

[0057] In the utility model, the chain plates within the first vertical spacing are double chain plates and single chain plates that are alternately distributed. In this embodiment, the chain plates are spaced from left to right in sequence: double chain plates, single chain plates, double chain plates, single chain plates...double chain plates. The chain plates within the second vertical spacing are single chain plates and double chain plates that are alternately distributed. In this embodiment, the chain plates are spaced from left to right in sequence: single chain plates, double chain plates, single chain plates, double chain plates...single chain plates. The strength of the double chain plates is also greater. At the same time, the chain plates from bottom to top are also double chain plates and single chain plates that are connected in sequence, so that the strength of the chain plates is good, and the chain plates, round steel and flat iron can form an integral structure with good strength, and at the same time, it does not affect its winding.

[0058] Each of the rollers 14 is disposed on the round steel 13 outside the double chain plate 111 .

[0059] See also Figure 2 , 3 As shown, a washer 114 is provided at the bottom within the transverse spacing 113 of the bottom double chain plate 111 , and the washer 114 is sleeved on the bottom round steel 13 .

[0060] In this embodiment, the round steel within the transverse spacing 113 of the bottom double chain plate 111 is no longer connected to other single chain plates 112. Therefore, there is a transverse spacing 113 between the double chain plates 111, which will affect the strength. Therefore, a gasket 114 is arranged inside to prevent the chain plate from deforming.

[0061] See also Figures 6 to 9As shown, the utility model also provides a special rolling shutter door for silver pavilions, including two parallel columns 116, a rotating shaft 115 rotatably mounted on the top of the two columns 116, and a positioning channel steel 117 opening inwardly is respectively provided on the side wall of each column 116, and the top plane of the positioning channel steel 117 is arranged close to the bottom plane of the rotating shaft 115;

[0062] It also includes the above-mentioned silver pavilion special rolling shutter door body, the chain plate 12 at the top of the main body 116 is connected to the outer surface of the rotating shaft 115, and the rollers 14 on both sides of the main body 116 are respectively rotatably set in the positioning channel steel 117 on each side.

[0063] In this embodiment, the column can be used as a door frame and installed on the side of the door of the silver kiosk, and the rotating shaft is located at the top of the door of the silver kiosk. The main body can be rolled up and unrolled by rotating the rotating shaft, that is, when the door needs to be opened, the rotating shaft rotates, driving the bottom of the main body to move upward, and the main body is gradually rolled up onto the rotating shaft to achieve the door opening action. When the door needs to be closed, the rotating shaft rotates, so that the bottom of the main body automatically moves downward under the weight, thereby driving the main body to unwind and achieve the door closing action. In this process, the positioning channel steel is set, and the inner end of the positioning channel steel is provided with a U-shaped groove, the groove width of the U-shaped groove matches the outer diameter of the roller, and the outer surfaces on both sides of the roller respectively abut against the inner walls corresponding to the two sides of the positioning channel steel. In this way, when the door body is retracted or extended, the U-shaped groove of the positioning channel steel limits the roller so that it can move along a predetermined trajectory, that is, the door body can be smoothly reeled and unreeled, and can also limit the position of the door body, so that when the rolling door is in a closed state and the rolling door is subjected to external force, it can be limited by the rotating shaft and the positioning channel steel to prevent the door body of the rolling door from moving back and forth and swinging (taking the view as an example), thereby playing an effective security role.

[0064] See also Figure 6 , 8 As shown, the two ends of the rotating shaft 115 are respectively provided with a brake disc 118 and a drive connection disc 119; the setting of the brake disc 118 can be provided with a brake on the outside thereof, and then the brake is used to clamp the brake disc, so as to limit the rotation of the rotating shaft, so that the rolling door can be limited to a predetermined position when unwinding or rewinding, thereby ensuring the safety of the rolling door during opening and closing. The setting of the drive connection disc 119 can be provided with a driving mechanism, and the driving mechanism is connected to the driving connection disc, and the driving mechanism drives the rotating shaft to rotate through the driving connection disc to realize the rewinding and unwinding of the main body.

[0065] See also Figure 6 , 7As shown, the end of the rotating shaft 115 is installed on the top of the corresponding column 116 via a bearing 120 and a bearing seat 121; the bottom of the bearing seat 121 is installed on the top of the column 116 via a mounting plate 122, and the end of the rotating shaft 115 is rotatably connected to the bearing seat 121 via the bearing 120; a plurality of reinforcing plates 123 are installed at the bottom of the mounting plate 122, and the side of the reinforcing plate 123 is connected to the side of the column 116.

[0066] In this embodiment, the shaft is connected through the bearing seat and the column, so that the shaft and the two columns form a U-shaped structure with an opening facing downward, which makes it strong in stability. Among them, the column will adopt U-shaped channel steel or C-shaped channel steel, which can effectively ensure the strength of the column, while reducing its weight and reducing its cost. The bearing seat is connected to the column through the mounting plate. Since the weight of the shaft and the door body needs to be transferred to the column through the bearing seat and the mounting plate, in order to increase the strength of the mounting plate and prevent the mounting plate from being deformed and damaged, the connection area and strength of the mounting plate and the column are increased by setting the reinforcing plate, wherein the reinforcing plate adopts a triangular plate structure with high strength. Preferably, in this embodiment, the column is a U-shaped channel steel, and the reinforcing plate is three pieces. Two fixed plates are respectively located on the front outer wall and the rear outer wall of the column, and another fixed plate is arranged on the inner wall of the column, and its top is connected and fixed to the bottom surface of the mounting plate to ensure the connection firmness of the mounting plate and the column, and at the same time, it can enhance the pressure bearing capacity of the mounting plate and ensure the strength of the mounting plate.

[0067] See also Figure 6 , 8 As shown in Figures 9 and 9, a plurality of connecting pieces 124 are provided on the outer surface of the rotating shaft 115, and the chain plates 12 at the top of the main body 1 are rotatably connected to the plurality of connecting pieces 124 via round steel bars 13. The number of the connecting pieces 124 matches the number of the chain plates 12 at the top of the main body 1, and each of the chain plates 12 is disposed beside a connecting piece 124.

[0068] In the utility model, one end of the connecting plate is welded to the outer surface of the rotating shaft, and a hole is set on the other end of the connecting plate, and the hole is opposite to the through hole of the chain plate. Each chain plate is set beside a connecting plate, and the round steel passes through the through holes of all the chain plates and the holes of all the connecting plates to connect the topmost chain plate and the connecting plate. Among them, rollers can be set at the ends of the round steel, and the rollers on both sides are used to limit the axial movement of the round steel to prevent the round steel from detaching from the connection between the chain plate and the connecting plate, thereby ensuring the connection stability between the chain plate and the connecting plate. Of course, since the connection between the topmost chain plate and the connecting plate of the main body is arranged close to the rotating shaft, limiters are also set at both ends of the round steel to limit the axial movement of the round steel. The limiters can be welding points, nuts, or limit pins, etc., without specific restrictions.

[0069] In the present invention, the middle part of the connecting piece has a notch, and the topmost chain plate of the main body is a single chain plate, and each single chain plate is inserted into the notch of each connecting piece, so that the connecting piece can be equivalent to a double chain plate, and the connection and fixation of the main body and the rotating shaft are realized. Of course, in the present invention, the connecting piece can also directly adopt a double chain plate, that is, the topmost chain plate of the main body is a double chain plate, and the main body is connected to the rotating shaft through the topmost double chain plate, that is, the top of the double chain plate is connected to the rotating shaft. Among them, in the present invention, the top of the connecting piece and the outer surface of the rotating shaft are welded and fixed.

[0070] In the utility model, the single and double chain plates cooperate with each other to form an integral structure with the round steel. In this way, if the chain plate wants to deviate to one side of the round steel, all the chain plates and flat irons within the vertical spacing must deviate at the same time. Therefore, the chain plate will not deviate laterally. At the same time, it will also be limited by the roller and the door frame after installation, and will not deviate along the round steel.

[0071] Embodiment 2: A rolling shutter door body and rolling shutter door for silver pavilions, the structure of which is basically similar to that of embodiment 1, except that transparent panels (not shown in the attached drawings) are installed on the front and rear surfaces of each flat iron, and the top and bottom of the transparent panels are respectively arranged close to the adjacent round steels. The transparent panels are arranged so that after the rolling shutter door is closed, the transparent panels can also play a certain role in preventing wind and rain, and will not affect the field of vision.
