Description

Technical Field

[0001] This application relates to the technical field of rolling doors, and particularly to a rolling door with high overall strength. Background Art

[0002] A rolling door is a common type of door widely used in commercial and industrial buildings. The rolling door includes a door curtain and a reel. When the rolling door is fully opened, the door curtain is curled inside the drum above the door, occupying less space and saving space.

[0003] The door curtain is composed of multiple curtain sheets. The upper hook of one curtain sheet is horizontally inserted into the lower hook body of another curtain sheet, and the upper hook and the lower hook in the two curtain sheets are buckled. Multiple curtain sheets are sequentially connected in series to form a rolling door with different heights. Currently, the curtain sheet is a hollow structure, resulting in poor strength of the curtain sheet, and thus poor overall strength of the door curtain. Summary of the Invention

[0004] In order to strengthen the strength of the curtain sheet, this application provides a rolling door with high overall strength.

[0005] A rolling door with high overall strength provided by this application adopts the following technical solutions:

[0006] A rolling door with high overall strength includes curtain sheets. A storage cavity is opened inside the curtain sheets. The storage cavity is a horizontally penetrating cavity. A clamping component is arranged inside the curtain sheets. The clamping component includes multiple clamping bars. The multiple clamping bars are distributed along the long side of the curtain sheets. The centers of the multiple clamping bars are on the same straight line. A clamping groove is opened inside the clamping bar. A steel bar is inserted into the multiple clamping grooves.

[0007] By adopting the above technical solutions, under the action of the clamping component, the steel bar can be clamped, thereby improving the connection stability between the clamping bar and the steel bar, and further improving the connection stability between the steel bar and the curtain sheet, reducing the situation of the steel bar slipping out of the curtain sheet. Under the action of the steel bar, the steel bar plays a supporting role for the curtain sheet, thereby increasing the strength of the curtain sheet and further enhancing the overall strength of the door curtain. Compared with the situation where the length of the clamping bar is consistent with the length of the steel bar, this application sets the clamping component as multiple clamping bars, which can save materials.

[0008] Preferably, the clamping bar is an arc bar, and an opening is opened on the outer wall of the clamping bar. The opening communicates with the clamping groove.

[0009] By adopting the above technical solution, under the action of the opening, the diameter of the clamping groove can be adjusted. When the diameter of the steel bar is slightly larger than that of the clamping groove, when the steel bar is inserted into the clamping groove, the opening will become larger accordingly, so as to adjust the diameter of the clamping groove, making the clamping groove fit and insert with the steel bar, thereby improving the applicability of the clamping component and enabling it to adapt to steel bars of multiple sizes.

[0010] Preferably, the opening directions of adjacent two of the clamping strips are arranged staggeredly.

[0011] By adopting the above technical solution, the staggered arrangement of the openings of adjacent two clamping strips can better clamp the steel bar. The multiple clamping strips with staggered openings respectively support the side walls of the steel bar in different directions, thus reducing the situation where the steel bar slides out from the openings of the clamping strips.

[0012] Preferably, a resisting component is arranged on the clamping component, and the resisting component is used for limiting the steel bar.

[0013] By adopting the above technical solution, under the action of the resisting component, the steel bar can be limited, thereby reducing the situation where the steel bar slides out from the clamping groove.

[0014] Preferably, the resisting component includes an installation box, a spring and a baffle. The installation box is fixed at the outer end of the outer wall of the clamping strip. An installation groove is formed in the outer wall of the clamping strip, and the installation groove communicates with the cavity of the installation box. One end of the baffle is inserted into the installation groove. One end of the spring is fixed on the inner wall of the installation box, and the other end of the spring is fixed on one side of the baffle.

[0015] By adopting the above technical solution, when the steel bar is inserted into the clamping groove, the steel bar applies a force to the baffle, driving the baffle to move away from the center of the steel bar and driving the slider to move along the sliding groove and the connecting groove until the inner wall of the baffle is flush with the inner wall of the clamping strip, facilitating the insertion of the steel bar into multiple clamping grooves. At this time, the spring is in a compressed state. After the steel bar completely enters the clamping component, the steel bar cancels the force applied to the baffle, and the spring gradually returns to its extended state, thereby driving the baffle to move towards the center of the steel bar, making the side wall of the baffle abut against the side wall of the steel bar. Therefore, it can not only facilitate the penetration of the steel bar into the clamping groove, but also the baffle plays a role in limiting the steel bar.

[0016] Preferably, a sliding groove is formed in the inner wall of the clamping strip, and a connecting groove is formed in the inner wall of the installation box. The connecting groove corresponds to the sliding groove. A slider is arranged on one side of the baffle close to the sliding groove, and the slider is movably inserted into the sliding groove.

[0017] By adopting the above technical solution, under the action of the slider, the sliding groove and the connecting groove, the situation where the baffle detaches from the clamping strip can be reduced. At the same time, it can also guide the movement of the baffle and reduce the deviation of the baffle during movement.

[0018] Preferably, there are two blocking components, and the two blocking components are distributed at both ends of the clamping component.

[0019] By adopting the above technical solution, there are two blocking components, so that the steel bars can pass through the clamping grooves from both ends of the clamping component. At the same time, the two blocking components can limit the two ends of the steel bars, reducing the situation that the steel bars slide out from both ends of the clamping grooves.

[0020] Preferably, there are two sliders, and the two sliders are distributed at the top and bottom of the baffle. The number of the sliding grooves and the connecting grooves is adapted to the number of the sliders.

[0021] By adopting the above technical solution, under the action of the two sliders, the connection stability between the baffle and the clamping strip and between the baffle and the installation box is further improved.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Under the action of the clamping component, the steel bars can be clamped, thereby improving the connection stability between the clamping strip and the steel bars, and further improving the connection stability between the steel bars and the curtain sheets, reducing the situation that the steel bars slide out from the curtain sheets. Under the action of the steel bars, the steel bars play a supporting role for the curtain sheets, thereby increasing the strength of the curtain sheets and further enhancing the overall strength of the curtain. Compared with the situation where the length of the clamping strip is the same as the length of the steel bars, the present application sets the clamping component as a plurality of clamping strips, which can save materials.

[0024] 2. When the steel bars are inserted into the clamping grooves, the steel bars exert a force on the baffle, driving the baffle to move away from the center of the steel bars, and driving the sliders to move along the sliding grooves and the connecting grooves until the inner walls of the baffle and the clamping strip are flush. This facilitates the insertion of the steel bars into multiple clamping grooves. At this time, the spring is in a compressed state. When the steel bars completely enter the clamping component, the steel bars cancel the force exerted on the baffle, and the spring gradually returns to its extended state, thereby driving the baffle to move towards the center of the steel bars, making the side wall of the baffle abut against the side wall of the steel bars. Therefore, it is convenient for the steel bars to pass through the clamping grooves, and at the same time, the baffle plays a role in limiting the steel bars. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Invention

[0030] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0031] The embodiment of the present application discloses a rolling door with high overall strength.

[0032] Embodiment 1:

[0033] Referring to Figure 1 and Figure 2 , a rolling door with high overall strength includes a curtain sheet 1. A storage cavity 11 is formed inside the curtain sheet 1. The extending direction of the storage cavity 11 is parallel to the long side of the curtain sheet 1. The storage cavity 11 is a horizontally penetrating cavity. A clamping assembly 2 is arranged inside the curtain sheet 1. The clamping assembly 2 is located in the storage cavity 11. The clamping assembly 2 includes a clamping strip 21. The outer wall of the clamping strip 21 is welded to the inner wall of the curtain sheet 1. In the embodiment of the present application, the clamping strip 21 is an arc strip. The long side of the clamping strip 21 is parallel to the long side of the curtain sheet 1. A clamping groove 211 is formed inside the clamping strip 21. An opening 212 is formed on the outer wall of the clamping strip 21. The extending direction of the opening 212 is parallel to the long side of the clamping strip 21. The opening 212 communicates with the clamping groove 211. There are multiple clamping strips 21. The multiple clamping strips 21 are distributed along the long side direction of the curtain sheet 1. The centers of the multiple clamping strips 21 are on the same straight line. The number of the clamping assemblies 2 is determined according to specific circumstances. In the embodiment of the present application, there are two clamping assemblies 2. The two clamping assemblies 2 are distributed along the width direction of the curtain sheet 1.

[0034] There is a steel bar 3 arranged inside the curtain sheet 1. The number of steel bars 3 is adapted to the number of clamping components 2. The two steel bars 3 are respectively connected to the adjacent clamping components 2. The steel bar 3 is arranged through a plurality of clamping strips 21. The steel bar 3 is inserted into the clamping groove 211 in a matching manner. Under the action of the clamping component 2, the steel bar 3 can be clamped, thereby improving the connection stability between the clamping strip 21 and the steel bar 3, and further improving the connection stability between the steel bar 3 and the curtain sheet 1, reducing the situation that the steel bar 3 slides out of the curtain sheet 1. Under the action of the steel bar 3, the steel bar 3 plays a supporting role for the curtain sheet 1, thereby increasing the strength of the curtain sheet 1 and further enhancing the overall strength of the curtain. The clamping strip 21 has a certain elasticity. Under the action of the opening 212, the diameter of the clamping groove 211 can be adjusted. When the diameter of the steel bar 3 is slightly larger than the diameter of the clamping groove 211, when the steel bar 3 is inserted into the clamping groove 211, the opening 212 will become larger accordingly, thereby adjusting the diameter of the clamping groove 211 to make the clamping groove 211 and the steel bar 3 fit and plug, thereby improving the applicability of the clamping component 2 and making it adaptable to steel bars 3 of multiple sizes.

[0035] In one clamping component 2, the openings 212 of two adjacent clamping strips 21 face in opposite directions. Compared with the situation where the length of the clamping strip is consistent with the length of the steel bar 3, in the present application, the clamping component 2 is arranged in the form of a plurality of clamping strips 21, which can save materials. The opposite openings 212 of two adjacent clamping strips 21 can better clamp the steel bar 3. The clamping strips 21 with opposite openings 212 respectively support both sides of the steel bar 3, thereby reducing the situation that the steel bar 3 slides out from the opening 212 of the clamping strip 21.

[0036] Embodiment 2: The difference between this embodiment and Embodiment 1 lies in the inconsistent structure of the clamping component 2.

[0037] Refer to Figure 3 and Figure 4 , two resisting components 4 are respectively arranged at both ends of the clamping component 2. The two resisting components 4 are respectively arranged on the outer walls of the outermost clamping strips 21 at both ends. The resisting component 4 includes an installation box 41 and a baffle 42. The installation box 41 is fixed at the end of the outer wall of the clamping strip 21 far from the opening 212. The installation box 41 is located at the outer end of the clamping strip 21. An installation groove 214 is formed on the outer wall of the clamping strip 21. The installation groove 214 is communicated with the cavity of the installation box 41. One end of the baffle 42 is inserted into the installation groove 214. The baffle 42 can enter the cavity of the installation box 41 along the installation groove 214. Sliders 421 are respectively fixed on the top surface and the bottom surface of the baffle 42. Correspondingly, sliding grooves 213 are respectively formed at the top and the bottom of the clamping strip 21. Connecting grooves 411 are respectively formed on the top surface and the bottom surface inside the installation box 41. The connecting grooves 411 correspond to the sliding grooves 213. The shapes of the connecting grooves 411 and the sliding grooves 213 are the same. The two sliders 421 are respectively inserted into the sliding grooves 213 close to them. The sliders 421 can move along the sliding grooves 213 and the connecting grooves 411.

[0038] Under the action of the slider 421, the chute 213 and the connecting groove 411, the situation where the baffle 42 disengages from the clamping strip 21 can be reduced. At the same time, the movement of the baffle 42 can also be guided, reducing the situation where the baffle 42 moves and deviates.

[0039] The resisting component 4 further includes a spring 43. One end of the spring 43 is fixed to the inner wall of the installation box 41, and the other end of the spring 43 is fixed to one side of the baffle 42. During the process of inserting the steel bar 3 into the clamping groove 211, the steel bar 3 applies a force to the baffle 42, driving the baffle 42 to move away from the center of the steel bar 3, and driving the slider 421 to move along the chute 213 and the connecting groove 411 until the inner wall of the baffle 42 is flush with the inner wall of the clamping strip 21, facilitating the insertion of the steel bar 3 into multiple clamping grooves 211. The spring 43 gradually resumes its stretched state. After the steel bar 3 completely enters the clamping component 2, the steel bar 3 withdraws the force applied to the baffle 42. At this time, the spring 43 resumes its stretched state, thereby driving the baffle 42 to move towards the center of the steel bar 3, so that the side wall of the baffle 42 abuts against the side wall of the steel bar 3. Correspondingly, the other side of the steel bar 3 abuts against another baffle 42. Under the action of the two baffles 42, the steel bar 3 can be limited, reducing the situation where the steel bar 3 slides out from both ends of the clamping groove 211.

[0040] The above are all the preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
