[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 7 As shown, a specific embodiment of a city sign device of the present invention includes a base 10, a support rod 11, a housing 20, a pull plate 30, a fixing rod 40, a rotating drum 60, a force storage member 62, a pull rope 63 and a locking mechanism;

[0031] The outer shell 20 is detachably mounted on the support rod 11 . The front and rear sides of the outer shell 20 are made of transparent material. The pull-out plate 30 is slidably mounted in the outer shell 20 and can slide along its vertical direction. The pull-out plate 30 is used to post identification information.

[0032] A fixing rod 40 is fixedly installed near the top of the housing 20, and a rotating drum 60 is rotatably installed on the fixing rod 40, and two rotating drums 60 are symmetrically arranged, and a connecting rod 61 is fixedly arranged on each rotating drum 60, and a force storage member 62 and a pull rope 63 are arranged on each connecting rod 61;

[0033] Therefore, when the pull plate 30 is pulled downward, the pull rope 63 drives the rotating drum 60 and the connecting rod 61 to rotate, and at the same time, the force storage member 62 stores force. When the pull plate 30 moves to the bottom, the force storage member 62 is in a state to be released.

[0034] The locking mechanism is installed on the fixed rod 40. When the pull rope 63 on one side is pulled, the rotating drums 60 on both sides are locked at the same time through the locking mechanism, so that they will not rotate, which is convenient for replacing the logo on the pull-out plate 30. When the pull rope 63 on the other side is pulled, the rotating drums 60 on both sides are unlocked at the same time through the locking mechanism, so that the force storage member 62 is released, driving the pull-out plate 30 to rise and return to its original position.

[0035] When in use, the pull plate 30 is pulled downward by the pull rod, so that it slides out of the shell 20 and descends to the bottom, so that it is convenient for workers to replace or maintain the logo on the pull plate 30. During the descent of the pull plate 30, the pull rope 63 is used to drive the rotating drum 60 to rotate, and at the same time, the force storage member 62 is charged. When the pull plate 30 moves to the bottom, the pull rope 63 on one side is pulled again and then released. The locking mechanism can lock the rotating drums 60 on both sides at the same time to prevent the force storage member 62 from releasing and causing the pull rope 63 to pull the pull plate 30 up. After the replacement is completed, the pull rope 63 on the other side is pulled and then released. The locking mechanism is unlocked, and the force storage member 62 is released, driving the rotating drums 60 on both sides to rotate, thereby winding up the pull rope 63, and the pull rope 63 drives the pull plate 30 to rise into the shell 20, completing the replacement of the identification information.

[0036] like Figures 1 to 3 The outer shell 20 is mounted on the support rod 11 by bolts, and two outer shells 20 are symmetrically arranged. The front and rear sides of the outer shell 20 are made of transparent material. In this embodiment, the material is glass, so as to facilitate the display of the identification information on the internal pull-out plate 30.

[0037] The outer shell 20 is an open structure at the bottom, and a partition is arranged near the top inside, thereby dividing the interior into an upper chamber 21 and a lower chamber 22. The pull-out plate 30 is slidably installed in the lower chamber 22 and can move along the length direction of the outer shell 20, and the lower end surface of the pull-out plate 30 is flush with the lower end surface of the outer shell 20.

[0038] A locking plate 31 is rotatably mounted at the bottom of the pull-out plate 30 , and an L-shaped buckle 32 is fixedly mounted at the bottom of the housing 20 . The locking plate 31 can be rotated to snap its edge into the gap of the buckle 32 , thereby locking the pull-out plate 30 .

[0039] like Figure 4 , Figure 5 and Figure 6 The fixing rod 40 is fixedly installed in the upper chamber 21 and arranged along the width direction of the outer shell 20. Two rotating drums 60 are symmetrically installed on the fixing rod 40. The rotating drum 60 can rotate along the axial direction of the fixing rod 40. A connecting rod 61 is fixedly installed on the side of the two rotating drums 60 that are away from each other. A force storage member 62 is sleeved on the outer side of the connecting rod 61. One end of the force storage member 62 is connected to the connecting rod 61, and the other end is connected to the outer shell 20. Therefore, when the rotating drum 60 rotates, the force storage member 62 can store force, and when the force storage member 62 is released, the rotating drum 60 can be driven to rotate.

[0040] In this embodiment, the force storage member 62 is a torsion spring. In other embodiments, it can also be a coil spring or the like.

[0041] A pull rope 63 is also wound around the outside of the connecting rod 61 , one end of the pull rope 63 is fixed to the connecting rod 61 , a through hole is provided between the upper chamber 21 and the lower chamber 22 , and the other end of the pull rope 63 passes through the through hole and is fixedly connected to the pull plate 30 .

[0042] The worker can hook the pull rod on the locking plate 31, rotate it to disengage the buckle 32, and then pull the pull plate 30 downward. The pull plate 30 will drive the pull ropes 63 on both sides to descend, so that when the pull ropes 63 are released, they will drive the rotating drum 60 to rotate. During the rotation, the force storage member 62 will store force until the pull plate 30 is separated from the shell 20 and lowered to a suitable height, which is convenient for the worker to replace the identification information.

[0043] Continue back Figure 5 and Figure 6 In this embodiment, the locking mechanism includes a groove 64 formed on the rotating drum 60. The groove 64 is located on the opposite surfaces of the two rotating drums 60, and each of the two rotating drums 60 is provided with a groove 64. The groove 64 is arc-shaped, and its internal depth gradually increases along the arc-shaped path direction (such as Figure 7 ), limiting plates 65 are provided on both sides of the groove 64.

[0044] A mounting plate 50 is rotatably mounted on the fixed rod 40, and the mounting plate 50 can rotate axially along the fixed rod 40, and the mounting plate 50 is arranged between the two rotating cylinders 60. An outer column 51 is slidably mounted on the mounting plate 50 along its axial direction, and a spring is installed between the outer column 51 and the mounting plate 50, one end of the spring is connected to the outer column 51, and the other end is connected to the mounting plate 50, and one end of the outer column 51 is located in the groove 64 of the left rotating cylinder 60, and the other end passes through the mounting plate 50, an inner column 52 is slidably mounted on the end of the outer column 51 away from the left rotating cylinder 60, and a spring is installed between the inner column 52 and the outer column 51, one end of the spring is connected to the inner column 52 and the other end is connected to the outer column 51, and the end of the inner column 52 away from the outer column 51 is located in the groove 64 on the right rotating cylinder 60.

[0045] A through hole is provided on the mounting plate 50, in which a gear 54 is rotatably installed. An upper slide plate 53 and a lower slide plate 55 are meshedly connected to the upper and lower sides of the gear 54 respectively. Teeth (not shown in the figure) are provided on the surfaces of the upper slide plate 53 and the lower slide plate 55 opposite to the gear 54. The upper slide plate 53 and the lower slide plate 55 are meshedly connected with the mounting plate 50 through the teeth. The upper slide plate 53 and the lower slide plate 55 are slidably matched with the mounting plate 50, so that the upper slide plate 53 and the lower slide plate 55 can move toward each other, and the upper slide plate 53 is fixedly connected to the inner column 52. Insert blocks 56 are provided at the moving ends of the upper slide plate 53 and the lower slide plate 55.

[0046] A locking plate 41 is fixedly mounted on the fixing rod 40 . The locking plate 41 is located between the mounting plate 50 and the rotating drum 60 on the right side. The locking plate 41 is a circular structure, and a plurality of locking grooves are evenly distributed in the circumferential direction on one side thereof facing the mounting plate 50 .

[0047] When it is necessary to lock the rotating drums 60 on both sides, the pull rope 63 on the left side is pulled downward, and the rotating drum 60 on the left side rotates. Due to the change in the depth of the groove 64, its inclined surface will force the outer column 51 to slide to the right, and the limiting plates 65 on both sides can prevent the outer column 51 from disengaging from the groove 64. The outer column 51 will simultaneously drive the inner column 52 to move to the right, so that the end of the inner column 52 abuts against the inner wall of the groove 64 on the right rotating drum 60. When the inner column 52 moves to the right, it will drive the upper slide plate 53 to move to the right. At this time, the plug block 56 at the end of the upper slide plate 53 just abuts against the locking groove on the locking plate 41, and the lower slide plate 55 moves to the left, and the plug block 56 at its end is just inserted into the plug hole 66 on the left rotating drum 60. Since the locking plate 41 is fixedly mounted on the fixing rod 40, the rotation of the mounting plate 50 and the rotating drums 60 on both sides is simultaneously restricted, and the pull-out plate 30 will not be pulled, thereby facilitating the replacement of the identification information.

[0048] When the replacement of the identification information is completed and the pull-out plate 30 needs to be retracted into the outer shell 20, the pull rope 63 on the right side is pulled downward, and the rotating drum 60 on the right side rotates, so that the inclined surface on the right groove 64 will force the inner column 52 to move to the left, and the inner column 52 will slide in the outer column 51. At the same time, the inner column 52 drives the upper slide plate 53 to move to the left, and the plug block 56 on the upper slide plate 53 disengages from the locking plate 41. At the same time, the lower slide plate 55 moves to the right, and the plug block 56 at its end disengages from the socket 66. At this time, the restrictions on the mounting plate 50 and the rotating drum 60 on both sides are released, and the force storage member 62 is released, driving the rotating drum 60 on both sides to rotate synchronously, and the pull rope 63 is reeled in. The pull rope 63 drives the pull-out plate 30 to rise and be retracted into the outer shell 20, completing the replacement of the identification information.

[0049] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
