Description

Technical Field

[0001] The present disclosure relates to the field of rolling gates, and more particularly, to a rolling gate. Background Art

[0002] Rolling gates are a relatively common door structure in the current prior art, mainly used in occasions that require large doors. They have the characteristics of a wide coverage area and low material cost, and can effectively achieve the function of a door. In the prior art, a rolling gate mainly consists of a door curtain, a slide rail, and a reinforcing rod. The reinforcing rod is arranged on the door curtain, and both ends of the reinforcing rod extend into the chute of the slide rail. Through the limiting effect of the slide rail, the vertical lifting of the door curtain is realized. When the rolling gate is in use, in the event of strong winds, the impact force of the airflow on the door curtain body is relatively large, and the door curtain will drive the reinforcing rod to shake violently, resulting in damage to the reinforcing rod due to collision with the slide rail. At the same time, it may also cause the reinforcing rod to come out of the chute of the slide rail, leading to the failure of the rolling gate. Summary of the Utility Model

[0003] The purpose of the present disclosure is to provide a rolling gate to at least partially solve the problems existing in the related art.

[0006] A winding assembly for unfolding or winding the door curtain body;

[0007] Slide rails are arranged on both sides of the door curtain body. Chutes are formed on the slide rails, and the edges on both sides of the door curtain body and both ends of the reinforcing rod are respectively slidably arranged in the chutes; and

[0008] A locking structure is arranged in the chute for fixing the reinforcing rod.

[0009] Optionally, the locking structure includes a locking rod, and the locking rod has a first position for avoiding the reinforcing rod and a second position for connecting with the reinforcing rod.

[0010] Optionally, the locking structure further includes a receiving groove formed at the bottom of the chute and a rotating shaft arranged in the receiving groove. The locking rod is swingably arranged in the receiving groove through the rotating shaft. A first connecting portion is arranged at one end of the locking rod, and a second connecting portion is arranged on the reinforcing rod.

[0011] Wherein, when in the first position, the locking rod and the first connecting portion are completely received in the receiving groove, and when in the second position, the first connecting portion is cooperatively connected with the second connecting portion.

[0012] Optionally, the first connecting portion is a plugging rod, and the second connecting portion is a plugging groove formed on the reinforcing rod.

[0013] Optionally, the texture unit protrudes outward relative to the curtain body, and the shape of the texture unit is one of a spherical shape, a cylindrical shape, and a prismatic shape; or,

[0014] The texture unit is recessed inward relative to the curtain body, and the texture unit is one of a spherical hollow, a cylindrical hollow, and a prismatic hollow.

[0015] Optionally, a particle structure is provided on the surface of the texture unit.

[0016] Optionally, the winding assembly includes a reel, a driving motor, and a housing.

Detailed implementation manners

[0031] The following will describe in detail the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, left, right" generally refer to the orientation of the relevant components in the actual use state, and specifically can refer to Figure 1 and Figure 2 the drawing directions of. "Inner and outer" can refer to the inner and outer of the contour of the corresponding component or its internal or external in the environment where it is located according to the specific context. In addition, when the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequence and importance.

[0033] As Figures 1 to 6 shown, the present disclosure provides a rolling shutter, including a curtain 1, a winding assembly 2, a slide rail 3 and a locking structure 4. Among them, the curtain 1 includes a curtain body 11 and a reinforcing rod 12. A plurality of reinforcing rods 12 are arranged at intervals in the vertical direction. A plurality of texture units 13 protruding outward or recessed inward are arranged on the surface of the curtain body 11. The texture units 13 are used to reduce the impact force of the airflow on the curtain body 11. The winding assembly 2 is used to unfold or wind the curtain body 11. The slide rails 3 are arranged on both sides of the curtain body 11. Chutes 31 are formed on the slide rails 3. The edges on both sides of the curtain body 11 and the two ends of the reinforcing rod 12 are respectively slidably arranged in the chutes 31. The locking structure 4 is arranged in the chutes 31 and is used to fix the reinforcing rod 12.

[0034] Through the above technical solution, when the airflow contacts the multiple texture units 13 that protrude outward or are recessed inward relative to the door curtain body 11, the texture units 13 can interfere with the airflow, so that the airflow that originally directly impacts the door curtain body 11 can be dispersed or changed in direction, thereby reducing the impact force of the airflow on the door curtain body 11. At the same time, the texture units 13 also increase the surface area of ​​the door curtain body 11, so that the contact area between the airflow and the door curtain body 11 is increased, and the impact force of the airflow can be effectively distributed, preventing the door curtain body 11 from shaking violently. In addition, the locking structure 4 provided in the slide groove 31 can fix the reinforcing rod 12 when the rolling shutter is in use, making the reinforcing rod 12 more stable while preventing the reinforcing rod 12 from escaping from the slide groove 31 of the slide rail 3. In this way, through the texture unit 13 and the locking structure 4, the reinforcing rod 12 and the door curtain body 11 can be made more stable, preventing the rolling shutter from failing due to violent shaking.

[0035] Rolling shutters usually have three states. The first is the use state, in which the winding assembly 2 unfolds the door curtain body 11, and the door curtain body 11 abuts against the ground to close the entrance and exit of the building. The second is the storage state, in which the winding assembly 2 winds the door curtain body 11, and the door curtain body 11 keeps moving away from the ground to open the entrance and exit of the building. The third is the semi-use state, in which the door curtain body 11 is neither completely wound nor completely unfolded, and a certain gap is left between the door curtain body 11 and the ground, and the rolling shutter partially opens the entrance and exit of the building.

[0036] The locking structure 4 may include a locking rod 41, which has a first position for avoiding the reinforcing rod 12 and a second position for connecting with the reinforcing rod 12. The locking rod 41 can avoid the reinforcing rod 12 in the first position, so that when the rolling shutter door switches between the storage state, the use state and the semi-use state, the locking rod 41 will not interfere with the movement of the reinforcing rod 12 and the door curtain body 11. When the rolling shutter door is in the use state or the semi-use state, the locking rod 41 can contact and fix the reinforcing rod 12 in the slide groove 31 in the second position, limit the reinforcing rod 12, and make the reinforcing rod 12 more stable.

[0037] In some embodiments, the locking structure 4 may further include a receiving groove 42 provided on the bottom of the slide groove 31 and a rotating shaft 43 provided in the receiving groove 42. The locking rod 41 is swingably provided in the receiving groove 42 via the rotating shaft 43. A first connecting portion 44 is provided at one end of the locking rod 41, and a second connecting portion 45 is provided on the reinforcing rod 12. In the first position, the locking rod 41 and the first connecting portion 44 are completely accommodated in the receiving groove 42. In the second position, the first connecting portion 44 is cooperatively connected with the second connecting portion 45. Since the locking rod 41 is swingably provided, the locking rod 41 can have two positions. For details, please refer to Figure 2 、 Figure 3 and Figure 4 , inFigure 2 In the case where the rolling shutter is in a semi - used state, Figure 3 In the case where the locking rod 41 is in the second position, the first connecting portion 44 can be connected to the second connecting portion 45, which serves to fix the reinforcing rod 12. In Figure 4 In the case where the locking rod 41 is in the first position, when in the first position, the locking rod 41 swings back into the receiving groove 42, and the first connecting portion 44 and the second connecting portion 45 are separated. Due to the limitation of the sliding groove 31, when the locking rod 41 is received in the receiving groove 42, the reinforcing rod 12 and the locking rod 41 do not come into contact.

[0038] When the locking rod 41 needs to be received in the receiving groove 42 for a long time, the locking rod 41 can be detachably connected to the groove wall of the receiving groove 42. The position of the receiving groove 42 can correspond to the position of the reinforcing rod 12 when the rolling shutter is in the used state. When the rolling shutter is in the used state or the semi - used state, since the position of the receiving groove 42 can correspond to the position of the reinforcing rod 12, after the locking rod 41 swings, the first connecting portion 44 and the second connecting portion 45 can be directly connected. When the rolling shutter needs to change from the used state or the semi - used state to the storage state, the locking rod 41 can be swung back into the receiving groove 42 in advance, and the first connecting portion 44 and the second connecting portion 45 are separated, so that the reinforcing rod 12 can move when the curtain body 11 is wound.

[0039] In some embodiments, the first connecting portion 44 can be a plugging rod, and the second connecting portion 45 is a plugging groove formed on the reinforcing rod 12. In this way, the first connecting portion 44 and the second connecting portion 45 form a plugging connection. There is no need to use additional fasteners (such as screws, bolts) or adhesives between the plugging - connected first connecting portion 44 and the second connecting portion 45, and it is also convenient for disassembly and maintenance, improving the assembly efficiency and flexibility. In other embodiments, the first connecting portion 44 can be a buckle, and the second connecting portion 45 can be a slot that can be snap - fitted with the first connecting portion 44.

[0040] In the present application, the connection manner between the locking rod 41 and the reinforcing rod 12 is not limited, as long as the locking rod 41 can fix the reinforcing rod 12 in the second position. In addition to the above - mentioned manner in which the reinforcing rod 12 and the locking rod 41 are connected through the first connecting portion 44 and the second connecting portion 45, the locking rod 41 can also completely penetrate the reinforcing rod 12 to be connected to the reinforcing rod 12 in the second position. Or, a space capable of sleeving the end of the reinforcing rod 12 can be formed at the end of the locking rod 41. When the locking rod 41 is in the second position, the end of the locking rod 41 can be sleeved on the end of the reinforcing rod 12 to be connected to the reinforcing rod 12.

[0041] The texture unit 13 may protrude outward relative to the door curtain body 11, and the shape of the texture unit 13 is one of spherical, cylindrical, and prism-shaped; or the texture unit 13 may be recessed inward relative to the door curtain body 11, and the texture unit 13 may be one of spherical hollow, cylindrical hollow, and prism-shaped hollow. Figure 5 , texture unit 13 is a columnar protrusion, refer to Figure 6 , the texture unit 13 is a spherical protrusion. The above-mentioned shapes are relatively regular and more suitable for large-scale processing on the door curtain body 11. At the same time, the edges of the texture unit 13 and the connection between the texture unit 13 and the door curtain body 11 can be smoothly transitioned. In this way, the edge of the texture unit 13 will not be too sharp, so that people will not be scratched by the texture unit 13 when touching the door curtain body 11, and it also prevents the texture unit 13 from damaging the door curtain body 11 or other texture units 13 during the winding and unfolding of the door curtain body 11. It should be understood that the present application is not intended to limit the shape of the texture unit 13, Figure 5 and Figure 6 Only two of the various shapes of the texture unit 13 are shown. In addition to the shapes mentioned above, other suitable shapes are also possible.

[0042] The surface of the texture unit 13 may be provided with a granular structure. The granular structure can improve the effect of the texture unit 13 in interfering with the airflow, and further reduce the impact force of the airflow on the door curtain body 11. At the same time, the granular structure can also further increase the contact area between the airflow and the door curtain body 11, and the impact force of the airflow can be further distributed.

[0043] The winding assembly 2 may include a reel 21, a drive motor 22 and a housing 23. The door curtain body 11 is connected to the reel 21. The drive motor 22 drives the reel 21 to rotate to unfold or wind up the door curtain body 11. The housing 23 is covered outside the reel 21 and is formed with a storage space for accommodating the door curtain body 11, the reel 21 and the drive motor 22. In this way, personnel can remotely control the drive motor 22 to switch the state of the rolling shutter door, which is more convenient to use. By integrating the reel 21, the drive motor 22 and the door curtain body 11 in the housing 23, the winding assembly 2 is more integrated and occupies a smaller volume. At the same time, the housing 23 also provides physical protection for the reel 21, the door curtain body 11 and the drive motor 22, that is, to prevent damage to them by external factors such as dust, moisture, and accidental collisions, thereby extending the service life of the winding assembly 2. The drive motor 22 may be a motor with automatic limit or overload protection, which can also improve the safety of the winding assembly 2 during use.

[0044] ​A first flange 24 and a second flange 25 extending radially outward along the reel 21 can be provided on the reel 21. The curtain body 11 is disposed between the first flange 24 and the second flange 25. Both ends of the reinforcing rod 12 are respectively abutted against the first flange 24 and the second flange 25. In this way, during the unfolding and winding processes of the curtain body 11, the first flange 24 and the second flange 25 can limit the reinforcing rod 12, and the first flange 24 and the second flange 25 indirectly limit the curtain body 11, preventing the curtain body 11 and the reinforcing rod 12 from shifting during the winding process.

[0045] The winding assembly 2 can further include a crank 26. The crank 26 is disposed at an end of the reel 21 away from the drive motor 22 and is used to manually unfold or wind the curtain body 11. With the manually operable crank 26, when facing the situation of the drive motor 22 failing, personnel can also manually switch the state of the rolling shutter, enabling them to handle more emergencies.

[0046] When the impact force of the airflow on the curtain body 11 is relatively large, the curtain body 11 will drive the reinforcing rod 12 to shake. To prevent the reinforcing rod 12 from colliding with the chute 31 and being damaged, an elastic contact member can also be provided on the groove wall of the chute 31 to prevent the reinforcing rod 12 from colliding with the chute 31 when moving. The elastic member here can be made of an elastic material such as rubber.
