DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Embodiment 1

[0024] Combined with Figures 1 to 5As shown in the figure, this embodiment provides a safety airbag cloth roll support device that can be quickly switched and adjusted, including a support 1. A rotating shaft 5 suitable for installing a turntable is provided on the support 1. A first turntable 2 and a second turntable 3 are slidably arranged on the rotating shaft 5, and a receiving space 4 suitable for placing the safety airbag cloth roll is formed between the first turntable 2 and the second turntable 3. It further includes: a fixing mechanism 8 and a width adjustment mechanism 9. Among them, the fixing mechanism 8 is detachably arranged on the outside of the first turntable 2 to facilitate replacing the cloth roll after disassembly; the width adjustment mechanism 9 is arranged on the outside of the second turntable 3, and the width adjustment mechanism 9 is suitable for making the second turntable 3 displace a corresponding distance along the axis direction of the rotating shaft 5 according to the width requirement of the cloth roll installed in the receiving space 4, so as to expand or shrink the receiving space 4, and further adapt to different cloth roll width requirements.

[0025] In this embodiment, the support 1 can be made of stainless steel pipe and is provided with a bending part. After bending, it can directly form the rotating shaft 5 for installing the turntable. The turntable includes a first turntable 2 and a second turntable 3. Among them, both the first turntable 2 and the second turntable 3 are suitable for sliding along the central axial direction of the rotating shaft 5. On the one hand, the second turntable 3 can be disassembled to facilitate replacing the cloth roll; on the other hand, the distance between the first turntable 2 and the second turntable 3 can also be adjusted to form the receiving space 4 of the support 1 for installing the safety airbag cloth roll. Bearings are arranged on the first turntable 2 and the second turntable 3 for connecting with the rotating shaft 5 to reduce the rotational friction.

[0026] Combined with Figures 1 to 2As shown, a fixing mechanism 8 is provided on the side of the first turntable 2 away from the second turntable 3. The fixing mechanism 8 is used to limit the displacement of the first turntable 2 in the direction away from the second turntable 3. Specifically, the fixing mechanism 8 includes a mounting body 81 provided with a threaded through hole 811 and a locking assembly disposed in the threaded through hole 811. The locking assembly includes a bolt member 82, a spring member 83, and a locking bead 84. The bolt member 82, the spring member 83, and the locking bead 84 are disposed in the threaded through hole 811, wherein the spring member 83 is disposed between the bolt member 82 and the locking bead 84. The locking bead 84 is adapted to expose the inner end of the threaded through hole 811 under the pressing of the bolt member 82 and the spring member 83 for matching with a locking groove 51 provided on the rotating shaft 5, thereby defining the position of the mounting body 81 on the rotating shaft 5. By rotating the bolt to move towards the rotating shaft 5, the locking bead 84 can be controlled to be locked in the locking groove 51 of the rotating shaft 5, so that the fixing mechanism 8 is fixed on the rotating shaft 5. On the contrary, by rotating the bolt to move away from the rotating shaft 5, the pressure of the locking bead 84 on the locking groove 51 can be controlled to decrease, so that the fixing mechanism 8 can be movable. In this embodiment, a plurality of the locking grooves 51 are provided on the rotating shaft 5 along the central axis direction, so that the locking bead 84 can be locked in different locking grooves 51 to adjust the position of the first turntable 2. Through this solution, the width between the first turntable 2 and the second turntable 3 can also be adjusted. In this embodiment, at least two of the locking assemblies are provided on the mounting body 81 outside the first turntable 2 to lock the fixing mechanism 8 simultaneously and prevent the fixing mechanism 8 from shaking.

[0027] In a preferred embodiment, a grating detection device 6 is provided on the first turntable 2 or the second turntable 3 for detecting the remaining amount of the fabric roll. The grating detection device 6 is connected to an alarm device 7 for giving a reminder when it detects that the remaining amount of the fabric roll is insufficient. The intelligence of the bracket device is improved by the grating detection device 6. The staff does not need to keep an eye on it at all times, which reduces the workload of the staff and has the advantages of convenience and stability.

[0028] Combined with Figures 1 to 2As shown, in one embodiment, the width adjustment mechanism 9 includes a housing 91, a support slide rail 92, and an elastic device 93. The housing 91 is detachably mounted on the rotating shaft 5. The support slide rail 92 is slidably inserted into the housing 91. The elastic device 93 is disposed between the support slide rail 92 and the housing 91 to provide a force towards the accommodating space 4 for the support slide rail 92. When the second turntable 3 slides outwards, the support slide rail 92 can be displaced outwards and compress the elastic device 93, so that the width of the accommodating space 4 increases. A convex ring member 94 cooperating with the support slide rail 92 is provided on the outer side of the second turntable 3. The convex ring member 94 is adapted to be inserted into the housing 91 and connected to the inner end of the support slide rail 92. Here, the width adjustment mechanism 9 can be detached from the free end of the rotating shaft 5 and is used for installing a cloth roll after detachment. The housing 91 is mounted on the rotating shaft 5 by a locking method similar to that of the fixing mechanism 8. For example, a threaded through hole 811 is provided on the housing 91 for installing the locking assembly, and a lock groove 51 matching the locking assembly is provided on the rotating shaft 5 on one side of the second turntable 3.

[0029] A step 921 is provided at one end of the support slide rail 92 close to the second turntable 3, and a limiting portion 911 is provided at the inner end of the housing 91 far from the second turntable 3. The elastic device 93 is disposed between the step 921 and the limiting portion 911, so that the elastic device 93 has a pre-tightening force towards the second turntable 3 on the support slide rail 92. When the width of the cloth roll is relatively large, on the one hand, the width of the accommodating space 4 can be adjusted by adjusting the positions of the fixing mechanism 8 and the width adjustment mechanism 9. On the other hand, the second turntable 3 can be toggled outwards, so that the convex ring member 94 on the outer side of the second turntable 3 presses against the support slide rail 92 and drives the support slide rail 92 to move outwards to compress the elastic device 93. Furthermore, the convex ring member 94 can enter the housing 91, and the second turntable 3 can be moved outwards by a certain distance to adjust the width of the accommodating space 4. In this embodiment, the elastic device 93 can adopt a spring. In this embodiment, the width of the accommodating space 4 can be automatically adjusted. Through the action of the elastic device 93, the second turntable 3 can be kept stable during adjustment and the shaking can be reduced.

[0030] Embodiment 2

[0031] Combined with Figures 3 to 5 As shown, compared with the previous embodiment, the difference in this embodiment is that the structure of the width adjustment mechanism 9 is different, and the way to achieve width adjustment is also different.

[0032] Specifically, in this embodiment, the width adjustment mechanism 9 includes a rotating end cover 95, a first spring 96, an outer housing 91, a bracket slide rail 92, a second spring 97, and a ball assembly 98. Among them, the rotating end cover 95 is connected to the second turntable 3, and the first spring 96 connects the outer housing 91 and the rotating end cover 95 to elastically connect the second turntable 3 and the outer housing 91. The bracket slide rail 92 is inserted into the outer housing 91, and a second spring 97 is provided between the outer housing 91 and the bracket slide rail 92 to make the bracket slide rail 92 have a pre-tightening force in the direction towards the second turntable 3. The ball assembly 98 is arranged on the bracket slide rail 92 and is adapted to connect the outer housing 91 and the rotating shaft 5. When the bracket slide rail 92 moves towards the second turntable 3, the ball assembly 98 is adapted to clamp the outer housing 91 and the rotating shaft 5 so that the width adjustment mechanism restricts the second turntable 3 from moving outwards. When the bracket slide rail 92 moves away from the second turntable 3 under the action of an external force, the ball assembly 98 cancels the connection between the outer housing 91 and the rotating shaft 5, so that the width adjustment mechanism 9 is adapted to slide left and right on the rotating shaft 5. Here, an inclined surface 912 matching the bracket slide rail 92 is provided inside one end of the outer housing 91 close to the second turntable 3 to facilitate the connection or disconnection of the ball assembly 98 and the outer housing 91. A convex block 99 is connected to the rotating end cover 95 for connection with the first spring 96. The ball assembly 98 of this embodiment includes a plurality of balls rolling on the bracket slide rail 92, and both the upper and lower sides of the balls protrude from the bracket slide rail 92.

[0033] In this embodiment, by controlling the relative position of the bracket slide rail 92 and the outer housing 91, the width adjustment mechanism 9 is fixed on the rotating shaft 5 or released from the fixed connection with the rotating shaft 5. When the bracket slide rail 92 slides towards the second turntable 3, the ball assembly 98 gradually contacts the inclined surface 912 and finally clamps on the inclined surface 912, so that the upper and lower sides of the balls in the ball assembly 98 are respectively clamped between the outer housing 91 and the rotating shaft 5 to fix the entire width adjustment mechanism 9 on the rotating shaft 5. On the contrary, when the bracket slide rail 92 slides away from the second turntable 3 under the drive of an external force, the balls slide outwards along the inclined surface 912, releasing the pressure on the rotating shaft 5, so that the width adjustment mechanism 9 can slide on the rotating shaft 5. Through this solution, the position of the width adjustment mechanism 9 on the rotating shaft 5 can be adjusted at any time, without being affected by the locking groove 51, and the operation of locking and removing the entire width adjustment mechanism 9 is simple and does not require the assistance of other tools. In addition, the first spring 96 provided between the outer housing 91 and the rotating end cover 95 plays an elastic pre-tightening role and also facilitates the fine adjustment of the width of the second turntable 3.

[0034] Through the solution of the present utility model, not only the efficiency of fabric roll replacement is improved and the applicability of the fabric roll support 1 is enhanced, but also the labor intensity of the operator is reduced, and the problems caused by untimely fabric roll replacement are decreased.

[0035] It should be understood that the above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model.

[0036] The above introduction of the drawings used in the embodiments only shows some embodiments of the present utility model and should not be regarded as a limitation of the scope. For those of ordinary skill in the art, without creative efforts, other related drawings can also be obtained based on these drawings.
