Abstract
Description
Technical Field
[0001] This utility model belongs to the field of support technology, and in particular relates to a continuous roll bag support. Background Technology
[0002] Roll bags are rolls of multiple bags linked together, widely used in supermarkets, convenience stores, and other retail and household applications due to their convenience, economy, and practicality. Currently, supermarkets place roll bags on insert bars or crossbars. When a user wants to take a bag, they pull on the edge of the bag and rotate it. If too much force is applied, too many bags may be pulled out, requiring manual rewinding. Alternatively, when tearing at the dividing line of the bag, the tearing process exerts a certain force on the roll bag. After tearing, unless the user's hand continues to press on the roll bag, it will continue to rotate on the bar due to inertia, causing too many bags to be pulled out and piled on the ground, easily getting dirty and inconvenient to reuse, resulting in waste. Utility Model Content
[0003] The purpose of this utility model is to provide a continuous roll bag support to solve the problem that after the required bag is torn off, the continuous roll bag will continue to rotate due to inertia, causing too many bags to be pulled out and fall to the ground, resulting in dirt and waste.
[0004] To achieve the above objectives, this utility model provides a continuous roll bag support, including a support rod, a sleeve, a rotation damping mechanism, and a rotating component. One end of the support rod is a free end, and the other end is a fixed end. The sleeve is fixedly installed on the side of the support rod near the fixed end. The rotation damping mechanism is rotatably connected to the sleeve with damping force. The rotating component is rotatably disposed on the side of the support rod near the free end. Multiple elastic arms are connected between the rotation damping mechanism and the rotating component, allowing the continuous roll bag to pass through the free end of the support rod and be fitted onto the elastic arms.
[0005] Furthermore, the rotary damping mechanism includes a rotating sleeve and a connecting cylinder. The rotating sleeve has a connecting hole, and an annular platform extends from one end of the connecting hole toward the axis. A mounting hole is provided through the center of the annular platform. The rotating sleeve is rotatably connected to the outer periphery of the sleeve through the mounting hole. The annular platform has multiple protrusions spaced apart on the side facing the connecting hole, and a groove is formed between two protrusions. The connecting cylinder includes a connecting post and a connecting cap. The diameter of the connecting cap is larger than that of the connecting post. A limiting member is provided at the joint of the connecting post and the connecting cap. The connecting cylinder passes through the support rod so that the connecting post extends into and is installed in the sleeve, and one end of the connecting cap is fixed in the connecting hole. The limiting member extends into the groove to limit the continuous rotation of the rotating sleeve.
[0006] Furthermore, the connecting cylinder is composed of two semi-cylindrical halves joined together, and the limiting member is provided at the connection between the two halves.
[0007] Furthermore, the semi-cylinder has a groove on the side of the connecting cap near the connecting post, and the side wall of the groove is a limiting member, which engages with the slot to form a limiting position.
[0008] Furthermore, the limiting member is a spring piece, with its bottom end located between the connecting post and the connecting cap, and one side of its top end extending into the slot to form a limiting position.
[0009] Furthermore, the connecting post is provided with external threads, the sleeve is provided with internal threads, and the connecting post is threadedly connected to the sleeve.
[0010] Furthermore, the rotating sleeve is provided with multiple mounting slots, the rotating component is provided with corresponding insertion slots, and the two ends of the elastic arm are detachably connected to the mounting slots and insertion slots.
[0011] Furthermore, the elastic arm is a steel bar, and the steel bar is generally arc-shaped.
[0012] Furthermore, the number of elastic arms is three.
[0013] Furthermore, it also includes a column, the fixed end of which is detachably mounted on the column.
[0014] The above-mentioned technical solutions of one or more of the roll bag support provided in this embodiment of the utility model have at least the following technical effects:
[0015] Because multiple elastic arms connect the rotary damping mechanism and the rotating component, the sleeve of the continuous roll bag enters from the free end of the support rod and is fitted onto the elastic arms. The multiple elastic arms provide radial support, which can stably support continuous roll bags with different inner diameters. The installation and disassembly operations are simple.
[0016] Because the sleeve is fixed to the side of the support rod near the fixed end, and the rotary damping mechanism is rotatably connected to the sleeve with damping force, the rotating component is located on the side of the support rod near the free end. When the user pulls a bag and rotates the entire roll bag, the roll bag will not rotate too fast, causing too much bag to be pulled out. When the user tears a complete bag, the roll bag will rotate due to inertia under tension, but the damping force of the rotary damping mechanism limits the continuous rotation of the rotating component and the elastic arm, keeping the roll bag stable and preventing it from rotating further. This avoids the roll bag from continuing to rotate if not held in time, causing too much bag to be pulled out and fall to the ground, effectively preventing dirt and waste of resources from the roll bag and improving the user experience.

[0032] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0033] In one embodiment of the continuous roll bag support of this utility model, please refer to... Figures 1 to 6 The continuous roll bag support includes a support rod 100, a sleeve 200, a rotation damping mechanism 300, and a rotating component 400. One end of the support rod 100 is a free end 110, and the other end is a fixed end 120. The sleeve 200 is fixedly installed on the side of the support rod 100 near the fixed end 120. The rotation damping mechanism 300 is rotatably connected to the sleeve 200 with damping force. The rotating component 400 is rotatably disposed on the side of the support rod 100 near the free end 110. Multiple elastic arms 500 are connected between the rotation damping mechanism 300 and the rotating component 400, so that the continuous roll bag passes through the free end of the support rod 100 and is fitted onto the elastic arms 500.
[0034] Specifically, because multiple elastic arms 500 are connected between the rotary damping mechanism 300 and the rotating component 400, the sleeve of the continuous roll bag enters from the free end 110 of the support rod and is fitted onto the elastic arm 500. The multiple elastic arms 500 provide radial support, which can stably support continuous roll bags with different inner diameters, and the installation and disassembly operations are simple. Since the sleeve 200 is fixed on the side of the support rod 100 near the fixed end 120, the rotary damping mechanism 300 is rotatably connected to the sleeve 200 with damping force, and the rotating component 400 is rotatably located on the side of the support rod 100 near the free end 110, when the user pulls a bag and rotates the entire continuous roll bag, the continuous roll bag will not rotate too fast, causing too much bag to be pulled out. When a user tears open a complete bag, the roll bag will rotate due to inertia under tension. However, the damping force of the rotation damping mechanism 300 limits the continuous rotation of the rotating part 400 and the elastic arm 500, keeping the roll bag stable and preventing it from rotating further. This avoids the roll bag from being pulled out too much and falling to the ground if it is not held down in time and continues to rotate, effectively preventing the roll bag from getting dirty and wasting resources, and improving the user experience.
[0035] Furthermore, the rotary damping mechanism 300 includes a rotating sleeve 310 and a connecting sleeve 320. The rotating sleeve 310 is provided with a connecting hole 311. An annular platform 312 extends from the hole wall at one end of the connecting hole 311 toward the axis. A mounting hole 313 is provided through the center of the annular platform 312. The rotating sleeve 310 rotates the outer periphery of the connecting sleeve 200 through the mounting hole 313. A plurality of protrusions 314 are provided at intervals on the side of the annular platform 312 facing the connecting hole 311, and a groove 315 is formed between two protrusions 314. The connecting cylinder 320 includes a connecting post 321 and a connecting cap 322. The diameter of the connecting cap 322 is larger than that of the connecting post 321. A limiting member 323 is provided at the joint of the connecting post 321 and the connecting cap 322. The connecting cylinder 320 passes through the support rod 100 so that the connecting post 321 extends into and is installed in the sleeve 200, so that one end of the connecting cap 32 is fixed in the connecting hole 311. The limiting member 311 extends into the slot 315 to limit the continuous rotation of the rotating sleeve 310.
[0036] Specifically, because the rotating sleeve 310 is rotatably connected to the sleeve 200 through the mounting hole 313, the connecting post 321 of the connecting cylinder 320 extends into the sleeve 200 and is fixedly installed, making the connecting cylinder 320 stable on the support rod 100. At this time, one end of the connecting cap 322 is located in the connecting hole 311 of the rotating sleeve, and the limiting member 323 located at the junction of the connecting cap 322 and the connecting post 321 extends into the slot 315 of the annular platform to form a limit. When the continuous roll bag is rotated under tension, it drives the elastic arm 500 to rotate, and the rotating sleeve 310 rotates together, causing the spaced protrusions 314 and the slot 315 to pass through the fixed limiting member 323 in sequence, so that the rotation of the rotating sleeve 310 has a certain resistance. After the user takes the required bag, he no longer pulls the continuous roll bag with force. At this time, the limiting member 323 is stuck in the slot 315, effectively preventing the rotating sleeve 310 from continuing to rotate, thereby limiting the rotation of the elastic arm 500 and the continuous roll bag, so that the continuous roll bag can quickly maintain stability.
[0037] Furthermore, the connecting cylinder 320 is composed of two semi-cylindrical halves 324 joined together, with a limiting member 324 located at the connection point of the two halves 324. Specifically, the two halves 324 facilitate the installation of the connecting cylinder 320 by joining them together in front of the connecting hole 311 and extending into the sleeve 200, without needing to enter from the free end of the support rod 110; if replacement is required, other parts do not need to be disassembled, and the two halves can be separated by removing the connecting column 321 from the sleeve 200, making the assembly and disassembly of the connecting cylinder 320 convenient.
[0038] Furthermore, the semi-cylinder 324 has a groove 325 on the side of the connecting cap 322 near the connecting post 321. The sidewall of the groove is a limiting member, and the sidewall of the groove engages with the slot 315 to form a limiting. Specifically, the connecting cap 322 abuts against the annular platform 312, and the protrusion 314 of the annular platform can extend into the groove 325, and the sidewall of the groove extends into the slot 315. When the rotating sleeve 310 rotates, the sidewall of the groove and the protrusion 314 are squeezed and then enter the slot 315 until the tension is less than the resistance, and the sidewall of the groove is located in the slot 315, forming a limiting and fixing the rotating sleeve 310.
[0039] Furthermore, the limiting component is a spring piece 326, with its bottom end located between the connecting post 321 and the connecting cap 322, and its top end extending into the slot 315 to form a limiting position. Specifically, the connecting cap is close to the annular platform, the bottom end of the spring piece is fixed at the joint of the half-cylinder, and the spring piece near the connecting post extends into the slot 315. When the rotating sleeve 310 rotates, the spring piece 326 and the protrusion 314 are elastically compressed and then enter the next slot 315. When the tension of the continuous roll bag is less than the resistance, the spring piece 326 is stable in the slot 315, fixing the rotating sleeve 310.
[0040] Furthermore, the connecting column 321 is provided with external threads, and the sleeve 200 is provided with internal threads on its inner side. The connecting column 321 is threadedly connected to the sleeve 200. Specifically, since the sleeve 200 is fixedly installed on the support rod 100, the connecting cylinder 320 is stabilized on the support rod 100 through the threaded connection, making the installation and disassembly of the connecting cylinder 320 simple.
[0041] Furthermore, the rotating sleeve 310 is provided with multiple mounting slots 316, and the rotating component 400 is provided with corresponding insertion slots 410. The two ends of the elastic arm 500 are detachably connected to the mounting slots 316 and the insertion slots 410. Specifically, the detachable connection facilitates the replacement of elastic arms 500 with different elasticity or different widths to adapt to continuous roll bags with different inner diameters and weights.
[0042] Furthermore, the elastic arm 500 is made of steel strips, and the steel strips are generally arc-shaped. Specifically, the steel strips have good supporting force and structural strength, thus improving service life. The arc-shaped structure can better fit the inside of the roll bag and be inserted into the rotating sleeve 310 and the rotating component 400.
[0043] Furthermore, there are three elastic arms 500. Specifically, the three elastic arms 500 are evenly distributed to provide balanced support and prevent the roll bags from becoming eccentric or tilted.
[0044] Furthermore, it also includes a column 130, on which the fixed end of the support rod 100 is detachably mounted. Specifically, the column 130 can be installed on the ground or a table, and the column 130 and the support rod 100 are designed at right angles, so that the roll bag is more stably fitted onto the elastic arm 500; the detachable design makes it easy to install the support rod 100 in different positions.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
