[0001] The utility model relates to the technical field of operation and maintenance, and in particular to a rotating convergence mechanism and a folding signboard. Background Art

[0002] At present, power production units often use standing "Operation" and "Under Maintenance" signs when overhauling equipment. Most of these signs are bulky and large in size, which are very inconvenient to use and extremely difficult to carry. They are made of thick aluminum alloy welded together, which takes up space when stored and needs to be carried from the equipment room to the maintenance area, which consumes a lot of manpower. Some units have replaced the metal signs with lighter identification cloths, but the identification cloths still need to be manually rolled up when recycled, which is inconvenient.

[0003] Therefore, a foldable sign is needed, which is small in size and easy to store. The sign can be retracted into a base, and the identification cloth inside the sign has an automatic rolling function. The overall access is convenient, the installation is fast, and the space occupied is small. It is suitable for a variety of maintenance areas. Utility Model Content

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] 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.

[0032] Example 1

[0033] Reference Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a rotating convergence mechanism.

[0034] The support assembly 100 includes a lower chassis 101, which provides support and accommodation for the entire device. A receiving groove 102 is fixedly provided on the surface of the lower chassis 101, and the entire locking assembly 200 is arranged in the receiving groove 102, and the locking assembly 200 provides a locking effect for the unfolding and storage of the marking cloth roll 302.

[0035] The driving rotating rod 201 is rotatably set in the accommodating groove 102, and the two ends of the driving rotating rod 201 are respectively torsionally connected to the inner wall of the accommodating groove 102, and the outer walls of the two ends of the driving rotating rod 201 are also fixedly installed with toothed rings 202, and the toothed rings 202 can rotate with the rotation of the driving rotating rod 201. The limiting unit 203 is set on one side of the toothed ring 202, and the marking cloth roll 302 is sleeved on the driving rotating rod 201 and one end of the marking cloth roll 302 is fixedly connected to the outer wall of the driving rotating rod 201.

[0036] When the marking cloth roll 302 needs to be pulled out, the driving rod 201 will inevitably be driven to overcome the torque and rotate. The limiting unit 203 can lock the rotating driving rod 201. During the rotation process accompanying the pulling out of the marking cloth roll 302, the driving rod 201 will not be affected by the limiting unit 203 and can rotate normally. The limiting unit 203 can prevent the driving rod 201 from reversing under the action of the torque.

[0037] After being pulled out, the marking cloth roll 302 can be prevented from automatically retracting under the action of the limiting unit 203, making the operation of the entire device simpler and more labor-saving, and the staff does not need to prevent the marking cloth roll 302 from returning to its original position while pulling it.

[0038] Example 2

[0039] Reference Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, but differs in that the structure of the supporting assembly 200 and the matching structure of the lifting assembly 100 are further optimized.

[0040] A limit slot 202a is fixedly provided on one side of the gear ring 202, an extension rod 202a-1 is fixedly connected to the end of the limit slot 202a, a rotating torsion block 202b is fixedly installed on the other end of the extension rod 202a-1, the rotating torsion block 202b itself is in torsion connection with the extension rod 202a-1, and the outer end of the rotating torsion block 202b is located between the teeth on the surface of the gear ring 202. When the gear ring 202 rotates following the rotation of the driving rotating rod 201, the gear ring 202 can move the rotating torsion block 202b, which is in torsion connection with the extension rod 202a-1, has a resetting elastic force, and will not affect the normal rotation of the gear ring 202. A shielding plate 202a-2 is fixed on the top of the limit slot 202a, which can play a certain shielding and protective role.

[0041] A mating slot 203a is fixedly opened on one side of the limit slot 202a, and a slider 203a-1 is arranged to slide in the mating slot 203a. An elastic telescopic rod 203b is fixedly arranged at the end of the slider 203a-1, and the other end of the elastic telescopic rod 203b is fixedly connected to the inner wall of the mating slot 203a. The elastic telescopic rod 203b can ensure that the slider 203a-1 has the ability to reset.

[0042] A blocking plate 204 is fixedly provided at the front end of the slider 203a-1. The blocking plate 204 is located on one side of the rotating torsion block 202b. The blocking plate 204 itself cannot move, and can limit the reverse rotation of the rotating torsion block 202b, thereby preventing the reverse rotation of the gear ring 202. A support plate 204a is provided on one side of the blocking plate 204, and the support plate 204a plays the role of reinforcing the blocking plate 204. An anti-slip groove 203a-2 is fixedly provided on the top of the slider 203a-1. Through the anti-slip groove 203a-2, the staff can better move the slider 203a-1 along the matching notch 203a. The movement of the slider 203a-1 drives the blocking plate 204 away from the rotating torsion block 202b, and finally causes the blocking plate 204 and the rotating torsion block 202b to be misaligned.

[0043] The blocking plate 204 can no longer restrict the rotating torsion block 202b at this time, so under the action of the torsion rotation, the extension rod 202a-1 starts to rotate and reset together with the gear ring 202 and the marking cloth roll 302 in a linked manner.

[0044] Example 3

[0045] Reference Figures 1 to 5, which is the third embodiment of the utility model. This embodiment is based on the above embodiment and adds a foldable sign.

[0046] The storage component 300 provides folding storage for the identification function of the device. Two folding storage grooves 304 are fixedly opened on the surface of the lower chassis 101. The inner wall of the folding storage groove 304 is fixedly connected with a matching rod 304a. A spring 304a-1 is fixedly installed at the end of the matching rod 304a. The other end of the spring 304a-1 is fixedly connected to the inner wall of the folding storage groove 304. The L-shaped vertical rod 301 is rotatably mounted on the matching rod 304a and can rotate and slide along the matching rod 304a. The L-shaped vertical rod 301 is stored in the folding storage groove 304 in the default state. When it needs to be unfolded, it only needs to be manually rotated and lifted. The L-shaped vertical rod 301 is rotatably mounted on the matching rod 304a through the rotating groove 301a opened inside. The clamping unit 303 is arranged on one side of the L-shaped vertical rod 301 to clamp the L-shaped vertical rod 301.

[0047] A hook 301c is fixedly provided on the side of the L-shaped vertical bar 301, and a hook groove 304c is provided at the bottom of the folding storage groove 304. In the storage state, the hook 301c can be embedded in the hook groove 304c without affecting the folding of the L-shaped vertical bar 301. A positioning hole 304b is fixedly provided on the side wall of the folding storage groove 304, and a positioning rod 304b-1 is elastically slidably provided in the positioning hole 304b. The positioning rod 304b-1 is elastically connected to the inner wall of the lower chassis 101 through a spring, and one end of the positioning rod 304b-1 passes through the lower chassis 101 and is located outside the lower chassis 101, and the other end extends into the folding storage groove 304.

[0048] An inclined block 305 is fixedly provided on one end of the positioning rod 304b-1 facing the inner wall of the folding storage groove 304, and the plane of the inclined block 305 faces the side of the spring 304a-1, and the inclined surface faces the direction of the L-shaped vertical rod 301. When the L-shaped vertical rod 301 is erected and starts to slide along the folding storage groove 304, it will first begin to contact the inclined surface of the inclined block 305, and use the inclined surface to push the inclined block 305 together with the positioning rod 304b-1 outward along the positioning hole 304b. At this time, the spring can also be squeezed to allow the positioning rod 304b-1 to obtain the elastic force to reset.

[0049] When the L-shaped vertical rod 301 has squeezed the inclined block 305, the inclined block 305 will bounce into the clamping groove 301b on the side wall of the L-shaped vertical rod 301 under the reset action of the positioning rod 304b-1, thereby clamping the L-shaped vertical rod 301. Since the other side of the inclined block 305 is a plane, the L-shaped vertical rod 301 can be firmly clamped unless the positioning rod 304b-1 is manually pulled. After the two L-shaped vertical rods 301 are fixed, the marking cloth roll 302 can be rotated and pulled out and connected to the hook 301c on the side wall of the L-shaped vertical rod 301, so that the marking cloth roll 302 can be unfolded for use.

[0050] When the sign needs to be retracted, just remove the identification cloth roll 302 from the hook 301c, then move the slider 203a-1, the identification cloth roll 302 will reset under the reverse twisting of the extension rod 202a-1, and then manually pull out the positioning rods 304b-1 on both sides to unlock the L-shaped pole 301. The L-shaped pole 301 will bounce back to its original position under the action of the spring 304a-1, and then the L-shaped pole 301 can be rotated back into the folding storage slot 304.
