[0002] At present, the warning signs used for equipment maintenance are mainly flat signs. This traditional sign generally has the following problems: Classification and hanging. The signs frequently used in the production site are mainly "Work Here" and "Operation". It is necessary to take out the corresponding number of signs from the tool room according to the actual situation on site, and the corresponding signs must be recalculated after the on-site safety measures are changed; the traditional signs are hard square structures, and there is a situation that when more signs are taken, they are easy to slip during transportation, and it is very easy to cut the palm; the traditional signs are heavy and have a hard and large square structure. If there is a large number of maintenance signs required, it is inconvenient to carry them with you, and there is a great loss of manpower and time.

[0003] In some maintenance scenarios, soft sign cloth is used instead of traditional sign boards. However, the unfolding and storage of the sign cloth still need to be manually rolled up. In addition, the sign cloth is light in material. When encountering strong outdoor winds, the simple hanging of the sign cloth is difficult to meet the needs of harsh environments.

[0004] Therefore, there is a need for a relatively small and portable structure, which is not easily affected by the environment, can function independently and can be automatically rolled up to meet the needs of the existing environment. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1

[0034] Reference Figures 1-2 , which is the first embodiment of the utility model, and this embodiment provides a self-locking mechanism.

[0035] The storage assembly 100 is used to recycle the unfolded indicator tape 103. The inner wall of the winding sleeve 101 is installed with a retractable rotating rod 102 for rotating torque. The outer wall of the retractable rotating rod 102 is rotationally connected to the indicator tape 103. The indicator tape 103 can be pulled to drive the retractable rotating rod 102 to rotate, thereby gradually pulling out the indicator tape 103.

[0036] The operating assembly 200 is sleeved and fixed on both ends of the retractable rotating rod 102 to cooperate with the subsequent locking function. The control platform 201 is located on both sides of the retractable rotating rod 102. The control platform 201 is fixedly connected to the inner wall of the winding sleeve 101 and is not affected by the torque rotation of the retractable rotating rod 102. The matching wheel 202 is fixedly connected to the retractable rotating rod 102 and the matching wheel 202 is located on the other side of the control platform 201. The locking unit 203 is arranged on the same side of the matching wheel 202, which plays a self-locking role in the rotation of the retractable rotating rod 102, ensuring that the indicating tape 103 will not rotate under the reverse torque accumulated in the retractable rotating rod 102 when it is pulled out, thereby ensuring the stability of the operation of the entire device.

[0037] Example 2

[0038] Reference Figures 1 to 4, which is the second embodiment of the utility model, is based on the previous embodiment, but differs in that the structure of the storage component 100 and the matching structure of the operating component 200 are further optimized.

[0039] The surface of the winding sleeve 101 is fixedly provided with a retracting groove 101a, which is connected to the inner wall of the winding sleeve 101. The indicating tape 103 fixed to the outer wall of the retracting rotating rod 102 can be pulled out through the retracting groove 101a. The control platform 201 is fixedly connected to the inner wall of the winding sleeve 101 and is not affected by the torsion rotation of the retracting rotating rod 102. The retracting rotating rod 102 passes through the control platform 201. At the end of the retracting rotating rod 102 on the other side of the control platform 201, a matching wheel 202 is fixedly provided. The rotation of the retracting rotating rod 102 can drive the matching wheel 202 to rotate synchronously.

[0040] A connecting shaft 201a is fixedly provided on one side of the control platform 201 facing the mating wheel 202. A limit tooth 204 is elastically and rotatably sleeved on the outer wall of the connecting shaft 201a. The limit tooth 204 itself is meshed with the mating wheel 202. The tip of the limit tooth 204 extends into the teeth of the mating wheel 202. When the mating wheel 202 moves normally in one direction, the mating wheel 202 can move the limit tooth 204 to ensure that it can pass normally. The rotation sleeve of the connecting shaft 201a and the limit tooth 204 itself is connected by a spring, so there is a limit to the rotation angle between the two. It can also be limited by adding any blocking protrusion between the two. When the mating wheel 202 wants to rotate under the torsion of the retractable rotating rod 102, the limit tooth 204 cannot be reversed, so the mating wheel 202 cannot be reversed under the action of the limit tooth 204.

[0041] A pulling rod 204a is fixedly arranged on the other side of the limit tooth 204, and the pulling rod 204a passes through the shell of the winding sleeve 101 and extends to the outer wall of the winding sleeve 101. A paddle 204a-1 is fixedly arranged on one end of the pulling rod 204a. By pulling the paddle 204a-1, the limit tooth 204 can be driven to translate so as to be misaligned with the matching wheel 202. At this time, the matching wheel 202 is no longer blocked by the limit tooth 204 and can be quickly reset under the action of torque, thereby driving the indication tape 103 to be rewound and reset.

[0042] A stabilizing protrusion 101b is fixedly provided at the bottom of the winding sleeve 101. The stabilizing protrusion 101b can be set to a relatively stable rectangular shape. A pull groove 101b-1 is fixedly provided inside the stabilizing protrusion 101b. The pull groove 101b-1 can be used as a handle for easy carrying. In some occasions, it is only necessary to pull out the indicating tape 103 of the device. A pulling member 103a is fixed to the front end of the indicating tape 103. The pulling member 103a can be set to any shape that is convenient for hanging. After the indicating tape 103 is pulled out by the pulling member 103a, the pulling member 103a is fixedly hung on the equipment of the working scene. When recycling is required, it is only necessary to remove the device and then pull out the paddle 204a-1 synchronously to drive the indicating tape 103 to be rolled and reset. The front and back sides of the indicating tape 103 correspond to different warning fonts, and only need to be flipped when facing different scenes.

[0043] Example 3

[0044] Reference Figures 1 to 6 , which is the third embodiment of the utility model. This embodiment is based on the above embodiment and adds a convergent type identification device.

[0045] The matching assembly 300 is used to provide the entire device with an overall autonomous operation function, without relying on special scenes or equipment, and can be automatically unfolded and provide identification functions. The auxiliary assemblies 301 are rotatably arranged on both sides of the winding sleeve 101, and a telescopic rod 301a is fixedly arranged at one end of the auxiliary assembly 301, and the other end of the telescopic rod 301a is slidably arranged in the winding sleeve 101. In the default state, the two auxiliary assemblies 301 and the telescopic rod 301a are in the storage state, which can save space and is easy to carry.

[0046] A hanging rod 302 is fixedly provided on one side of the auxiliary assembly 301, and a folding rod 303 is rotatably provided at the end of the hanging rod 302. When the auxiliary assembly 301 is stored, the folding rod 303 maintains a horizontal position. A magnetic end 303c is fixedly provided at the end of the folding rod 303. Under the action of the magnetic end 303c, the folding rod 303 maintains an adsorption state and is not easy to shake, which can play a certain role in stabilizing the auxiliary assembly 301.

[0047] A stop bead 302a is elastically embedded inside the hanging rod 302, and a matching groove 303a is fixedly opened on the inner wall of the folding rod 303. The stop bead 302a itself is a smooth sphere, so the folding rod 303 will not be subject to much resistance during the rotation process, and the stop bead 302a can be pressed inside the hanging rod 302 through the spring. Once the matching groove 303a rotates to the position of the stop bead 302a, the stop bead 302a will pop out and enter the matching groove 303a. At this time, the folding rod 303 is in the unfolded state. This design can ensure that the folding rod 303 can maintain a certain stability in the unfolded state without loosening or shaking.

[0048] When the whole device needs to be unfolded, the auxiliary assembly 301 can be pulled out with a little force, and then the auxiliary assembly 301 is rotated to a desired angle, and the folding rod 303 is rotated, and the indicating tape 103 can be pulled out and fixed with the hanging groove 303b provided on the surface of the folding rod 303. The pulling member 103a can be set to any shape that is convenient for hanging, without limitation.

[0049] At this time, the whole device is unfolded to prevent it from being in the form of an independent signboard, and the stabilizing protrusion 101b can ensure that the device is placed stably and will not fall over.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0051] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0052] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
