[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "degree", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] Reference Figure 1-5An embodiment of the present invention provides a multi-purpose signboard for a maintenance operation site, including a signboard body, the signboard body including a layout frame 2 and a layout card 1 slidably set on the layout frame 2.

[0029] Specifically, at the maintenance site, the signboard body is installed at the construction site, and the information on the signboard body is used to remind passers-by. This is a prior art and will not be described in detail. However, the signboard body in the prior art is a one-piece body. When the information on the signboard body needs to be replaced, the entire signboard body needs to be replaced. One of the core innovations of the embodiment of the utility model is that the signboard body is provided with a layout frame 2 and a layout card 1. The layout frame 2 has a mounting groove 3 on its surface and an opening on its side. The layout card 1 is forced to enter the mounting groove 3 from the side opening of the mounting groove 3. That is, the layout card 1 is installed on the layout frame 2 by pushing and pulling. When connected, the layout card 1 is located in the mounting groove 3. The front opening of the mounting groove 3 can display the layout content of the layout card 1. The purpose of this arrangement is that if the situation at the work site changes, only the layout card 1 needs to be replaced by pulling and pulling, without having to replace the entire signboard body, thereby facilitating the replacement of the layout information of the signboard body. Moreover, the layout card 1 is smaller in size than the signboard body and is easier to store.

[0030] In actual use, the connection between the layout card 1 and the layout frame 2 is not stable, so a fixing component is provided on the layout frame 2. The fixing component connects the layout frame 2 and the layout card 1. When the layout card 1 is completely in contact with the layout frame 2, the fixing component fixes the layout card 1 to the layout frame 2. The fixing component can be a part such as a screw. By providing screw holes on the back of the layout frame 2, the layout frame 2 and the layout card 1 are fixedly connected using screws. This makes the connection between the layout card 1 and the layout frame 2 more stable and also facilitates the installation and removal of the layout card 1.

[0031] As an alternative to the above-mentioned method of fixing the layout card 1 by screws, preferably, the fixing assembly includes a check block 4 slidably set on the layout frame 2, a first elastic member 5 is provided between the check block 4 and the layout frame 2, and the check block 4 is located on the movement stroke of the layout card 1. Specifically, a sliding groove 6 is provided on the inner top wall of the installation groove 3, the check block 4 is slidably set in the sliding groove 6, and a slope is provided on the part of the check block 4 located outside the sliding groove 6, and the slope end faces the direction in which the layout card 1 enters the layout frame 2. A first elastic member 5 is provided in the sliding groove 6, the first elastic member 5 connects the check block 4 and the layout frame 2, and is preferably a spring. The size of the sliding groove 6 is larger than the size of the check block 4, so that the check block 4 can fully enter the sliding groove 6. The effect of such a setting is that when the layout card 1 is installed, a force is applied to the layout card 1 in the direction of the installation groove 3. Since the slope of the check block 4 is located on the movement stroke of the layout card 1, the layout card 1 and the check block 4 are inclined. After the surfaces are in contact, the check block 4 enters the sliding groove 6 to avoid it and accumulates force on the first elastic member 5 so that the check block 4 abuts against the upper end of the layout card 1. When the layout card 1 completely enters the layout frame 2, the check block 4 no longer abuts against the upper end of the layout card 1, so that the check block 4 is no longer subjected to the force in the direction of the first elastic member 5. The first elastic member 5 automatically resets the check block 4 due to its own elastic force. If the layout card 1 is subjected to the force in the direction of the check block 4, the check block 4 cannot enter the sliding groove 6 due to the abutment with the right-angled edge of the check block 4, that is, the layout card 1 cannot move in the direction of the check block 4, thereby achieving the locking of the layout card 1 and stably connecting the layout card 1 to the layout frame 2.

[0032] To facilitate removal of the layout card 1, the check block 4 is provided with an unlocking member for releasing the locking effect of the check block 4 on the layout card 1. The unlocking member acts on the check block 4. Preferably, a force is applied to the check block 4 to re-enter the sliding slot 6, thereby releasing the locking effect of the check block 4 on the layout card 1. This allows the layout card 1 to move toward the check block 4, thereby releasing the layout card 1 from the layout frame 2.

[0033] Preferably, the unlocking member includes a connecting member 7 fixed to the check block 4, and a lifting key 8 is fixed to the connecting member 7. Specifically, the connecting member 7 is L-shaped, and the connecting member 7 passes through the upper end of the layout frame 2 and passes through the sliding groove 6 to be fixed to the end face of the check block 4. The lifting key 8 is semi-annular, provided on the connecting member 7, and located in a direction away from the layout frame 2. When the check block 4 locks the layout card 1, the lifting key 8 applies a force to the connecting member 7 and the check block 4 to slide toward the inside of the sliding groove 6, that is, a vertical upward force, so that the connecting member 7 drives the check block 4 away from the layout card 1 until the check block 4 completely enters the sliding groove 6. The effect of such a setting is that when the layout card 1 needs to be removed, the check block 4 can be unlocked by simply applying a force to the lifting key 8. At the same time, the layout card 1 can be pulled toward the outside of the installation slot 3 to remove the layout card.

[0034] As another embodiment of the present utility model, a first sliding rod 9 and a fixed block 13 are slidingly provided on the layout frame 2, a second sliding rod 10 is provided on the fixed block 13, a first wedge surface 11 is provided on the first sliding rod 9, a second wedge surface 12 is provided on the second sliding rod 10, the second wedge surface 12 is on the movement range of the first wedge surface 11, and the layout card 1 is located on the movement range of the fixed block 13. Specifically, the first slide bar 9 is vertically arranged on one side of the layout frame 2 and can slide on the layout frame 2. A fixing groove 20 is provided on the inner side wall of the mounting groove 3 away from the open end. The fixing block 13 is slidably arranged in the fixing groove 20. The second slide bar 10 is fixedly connected to the fixing block 13. A second wedge surface 12 is provided on the end of the second slide bar 10. The first wedge surface 11 is provided on the end of the first slide bar 9 close to the fixing block 13. When a vertical upward force is applied to the first slide bar 9, so that the first slide bar 9 moves upward with the first wedge surface 11, the first wedge surface 11 and the second wedge surface 12 are in contact with each other. After the two wedge-shaped surfaces 12 abut against each other, a force is applied to the first wedge-shaped surface 11, causing the fixed block 13 to move along the fixed groove 20 toward the layout card 1. Because the layout card 1 is located on the movement stroke of the fixed block 13, the layout card 1 moves toward the open end of the installation groove 3 after being subjected to the force until the edge of the layout card 1 exceeds the layout frame 2. Since the layout card 1 completely enters the layout frame 2 during installation, when the layout frame 2 is removed, there is no force point on the layout card 1. In this way, by applying a force to the edge of the layout card 1, the layout card 1 can be removed from the layout frame 2.

[0035] Furthermore, a second elastic member 14 is provided between the fixed block 13 and the layout frame 2. The second elastic member 14 is located at the end of the fixed block 13 away from the layout card 1 and is fixedly connected to the layout frame 2. The second elastic member 14 is preferably a spring. When the first slide bar 9 moves vertically upward, the second wedge surface 12 is subjected to force to drive the fixed block 13 toward the layout card 1, which accumulates force in the second elastic member 14. When the first wedge surface 11 and the second wedge surface 12 move away from each other, the second elastic member 14 returns to its original state due to its own elastic force, causing the fixed block 13 to move away from the layout card 1, thereby achieving automatic reset of the fixed block 13 and the second slide bar 10.

[0036] Furthermore, the first slide bar 9 is fixedly connected to the connecting member 7. Specifically, the end of the first slide bar 9 away from the first wedge surface 11 is fixedly connected to the connecting member 7, and the distance between the first wedge surface 11 and the second wedge surface 12 in the initial state is smaller than the distance required for the check block 4 to fully enter the sliding groove 6. The effect of this arrangement is that when the lifting key 8 is subjected to a vertical upward force, it will drive the connecting member 7 to move upward. During its upward movement, since the distance between the first wedge surface 11 and the second wedge surface 12 in the initial state is smaller than the distance required for the check block 4 to fully enter the sliding groove 6, the first wedge surface 11 and the second wedge surface 12 will abut against each other only after the check block 4 fully enters the sliding groove 6, thereby pushing the layout card 1 toward the opening of the installation slot 3. In this way, only a vertical upward force needs to be applied to the lifting key 8 to meet the disassembly requirements, making it more convenient to remove the layout card 1.

[0037] To further enhance the fixing effect, a limiting portion 15 is provided on the back of the layout card 1, and a limiting groove 16 is provided on the layout frame 2 to cooperate with the limiting portion 15. The limiting portion 15 is provided on the back of the layout card 1 and has the same length as the layout card 1. The limiting portion 15 has a T-shaped cross-section. Preferably, there are two limiting portions 15 evenly distributed on the layout card 1. The layout frame 2 is provided with a limiting groove 16 to cooperate with the limiting portion 15. When the layout card 1 is connected to the layout frame 2, the limiting portion 15 is located within the limiting groove 16. Due to the T-shaped structure of the limiting portion 15, the layout card 1 cannot escape the restraint of the layout frame 2, thereby strengthening the stability between the layout card 1 and the layout frame 2.

[0038] In order to meet the occasional installation and removal requirements of the sign body at the maintenance site, a bracket is provided on the sign body, and a plurality of mounting screw holes 19 are arranged in an array on the bracket. The bracket includes a support rod 17 and a base 18. The base 18 is disc-shaped and in direct contact with the ground. The support rod 17 is fixedly connected between the base 18 and the layout frame 2. The support rod 17 is made according to the required length. A plurality of mounting screw holes 19 are arranged in an array on the base 18 about the support rod 17. When there is a need to install a sign at the maintenance site, the screws are driven through the mounting screws and nailed into the ground to complete the installation of the sign body. When it needs to be removed, the screws can be removed to facilitate replacement at the maintenance site.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
