[0002] Bulletin board refers to the display goods for posting and publishing official documents, announcements, notices and other prompt contents in places with large flow of people, which is generally divided into two types, one is large bulletin board, which is mainly erected beside the gate, at the main intersection and other places, and is used for large-scale notification and announcement, and the other is unit bulletin board or class bulletin board, which is generally pasted or hung on the wall surface and is used for small-scale notification and prompting.

[0003] A bidding bulletin board is disclosed in the Chinese utility model patent with publication number CN213150267U, which relates to the field of bulletin boards. The bidding bulletin board includes a fixed seat, two support rods are symmetrically welded to the lower surface of the fixed seat, a base is welded to the bottom end of the support rod, a placement groove is formed in the front surface of the fixed seat, two fixed strips are symmetrically fixedly connected to the front surface of the fixed seat, a protective frame is slidably connected between the two fixed strips, a transparent protective plate is fixedly connected to the inner wall of the protective frame, a fixed block is fixedly connected to the front surface of the fixed seat, and the fixed seat is provided with a transmission assembly and is transmissionally connected with a movable block through the transmission assembly. The transparent protective plate on the inner wall of the protective frame covers the front surface of the placement groove, thereby effectively protecting the posted paper in the placement groove from falling due to wind or accidental touching by viewers.

[0004] According to the related technology described above, the inventors believe that the following defects exist: The above-mentioned device protects the posted paper by sliding the protective frame left and right. When pasting a new posted paper, the staff needs to completely remove the protective frame and paste the new posted paper. In actual use, when a single person operates, the staff needs to support the protective frame with the support rod, which is complicated to operate and easy to damage the protective frame, resulting in poor user experience. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a bidding bulletin board.

[0006] The above technical purpose of the utility model is achieved by the following technical scheme: a bidding bulletin board, including a base, a support rod mounted on the base, and a fixed seat mounted on the support rod, a placement groove is formed in the side wall of the fixed seat, a protective frame is hingedly connected to the side wall of the fixed seat, a transparent protective plate is arranged on the side wall of the protective frame, a connecting rod is fixedly connected to the side wall of the protective frame, a connecting groove matched with the connecting rod is formed in the side wall of the fixed seat, and a limiting assembly for limiting the connecting rod is arranged on the fixed seat.

[0007] When the staff needs to paste the announcement paper, the staff needs to close the limiting assembly and pull the protective frame, so that the protective frame and the transparent protective plate are gradually rotated and separated from the fixed seat. At this time, the staff only needs to loosen the protective frame, so that the announcement paper can be pasted on the inner wall of the placing groove. When the staff finishes pasting, the staff only needs to reset the protective frame, so that the limiting assembly automatically limits the protective frame, thereby improving the use experience of the staff.

[0008] Further, a limiting slot is formed in the inner top wall of the connecting slot, the limiting assembly comprises a limiting rod slidingly arranged in the limiting slot, a compression spring fixed at one end of the limiting rod, and a driving device arranged on the fixed seat for driving the limiting rod, the other end of the compression spring is fixed on the inner top wall of the limiting slot, and an inclined surface is formed on the bottom surface of the limiting rod and the edge of the side wall near the opening of the limiting slot.

At this time, the staff only needs to pull the protective frame, so that the connecting rod and the connecting slot are separated, thereby improving the use experience of the staff.

[0013] Further, a fixing slot is formed in the inner wall of the driving slot, a fixing block is slidingly arranged in the fixing slot, and the fixing block is fixed with the driving rod.

[0014] Further, an arc-shaped slot matched with the fixing block is formed in the inner wall of the fixing slot.

[0015] By adopting the technical scheme, when the staff does not need to use the driving rod, the staff only needs to loosen the driving rod, so that the driving rod is reset under the action of the compression spring.

[0016] Further, the driving rod comprises a moving rod slidingly arranged in the driving groove and a ring-shaped block rotatably arranged on the side wall of the moving rod, and the ring-shaped block is fixed with the connecting rope.

[0017] By adopting the technical scheme, when the staff rotates the moving rod, the moving rod and the ring-shaped block slide relative to each other, so that the probability that the connecting rope rotates with the moving rod when the staff rotates the moving rod is reduced, and the probability that the connecting rope is stuck is further reduced.

[0018] Further, the end of the moving rod is fixed with a handle for reducing the difficulty of moving the moving rod for the staff.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the application, when the staff needs to paste the announcement paper, the staff needs to close the limiting assembly and pull the protective frame, so that the protective frame and the transparent protective plate are gradually rotated and separated from each other. At this time, the staff only needs to loosen the protective frame, so that the announcement paper can be pasted on the inner wall of the placing groove. When the staff finishes pasting, the staff only needs to reset the protective frame, so that the limiting assembly automatically limits the protective frame, thereby improving the use experience of the staff.

[0021] 2. In the application, when the staff finishes pasting, the staff only needs to reset the protective frame, so that the connecting rod is gradually reset and connected with the connecting groove, so that the connecting rod gradually inclines. At this time, the limiting rod moves upward in the connecting rod and moves completely into the limiting groove. Then, when the limiting groove and the limiting hole are opposite, the limiting rod moves downward under the action of the compression spring and is connected with the limiting hole, so that the connecting rod is kept stable.

[0022] 3. In the application, when the staff needs to open the protective frame, the staff needs to press the driving rod, so that the driving rod and the connecting rope move towards the transparent protective plate, and the limiting rod connected with the connecting rope gradually moves upward and is separated from the limiting hole. At this time, the staff only needs to pull the protective frame, so that the connecting rod and the connecting groove are separated, thereby improving the use experience of the staff.

One end of the compression spring 52 is fixed on the upper surface of the limiting rod 51, and the other end of the compression spring 52 is fixed on the inner top wall of the limiting groove 42.

[0033] When the staff finishes pasting, the staff only needs to reset the protective frame 3, so that the connecting rod 4 is gradually reset and connected with the connecting groove 41, thereby making the connecting rod 4 gradually incline. At this time, the limiting rod 51 moves upward under the action of the connecting rod 4 and is completely moved into the limiting groove 42. Then, when the limiting groove 42 is opposite to the limiting hole 53, the limiting rod 51 moves downward under the action of the compression spring 52 and is connected with the limiting hole 53, thereby making the connecting rod 4 stable.
