Description

Technical Field

[0001] This utility model relates to the field of road traffic technology, and in particular to an indicator device. Background Technology

[0002] Traffic signs are essential road traffic management facilities, primarily used to regulate traffic order and guide driving directions, playing a crucial role in ensuring smooth traffic flow and driving safety. Most existing traffic signs are made using aluminum sheet substrates with reflective film overlays, and then fixed to supporting columns using U-shaped clamps or direct welding, resulting in low installation and dismantling efficiency.

[0003] To facilitate the installation and replacement of traffic signs, the related technology discloses a traffic sign, including a support rod, a connector, a mounting plate, and a sign. The connector is fixedly installed on the upper end of the support rod, and a vertically arranged slot is provided on one side of the support rod. One end of the mounting plate is connected to the sign, and the other end can be inserted into the slot. The installation and disassembly time of the sign can be shortened by setting the mounting plate and the connector to be plugged into each other.

[0004] In the aforementioned traffic sign, after one end of the mounting plate is inserted into the slot, a bolt needs to be inserted horizontally into the slot, and a nut is connected to the end of the bolt that protrudes from the connector to fix the mounting plate to the connector. In actual construction, this fixing method requires construction workers to carry tools to work at height and use tools to tighten the nut at height, which is inconvenient to operate and poses safety hazards such as tools falling and injuring people.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes an indicating device, comprising:

[0008] Signage;

[0009] Hollow base body;

[0010] The connector includes a connecting part, a first plug-in part, and a second plug-in part. The connecting part is connected to the indicator sign, and both the first plug-in part and the second plug-in part are fixedly connected to the connecting part and can be inserted into the hollow base.

[0011] A clamping assembly is disposed in a hollow seat body and includes a first clamping member and a second clamping member. At least one of the first clamping member and the second clamping member is movably connected to the hollow seat body so that the first clamping member can abut against the first insertion portion and the second clamping member can abut against the second insertion portion.

[0012] Optionally, at least one of the first clamping member and the second clamping member is slidably connected to the hollow base.

[0013] Specifically, the clamping assembly also includes a guide member, which is horizontally disposed through the hollow base body, and the first clamping member and the second clamping member are both slidably connected to the guide member.

[0014] More specifically, the clamping assembly also includes an adjusting member, which is horizontally disposed through the hollow base. The first clamping member and the second clamping member are both threadedly connected to the adjusting member. Rotating the adjusting member can drive the first clamping member and the second clamping member to slide towards or away from each other along the guide member.

[0015] Optionally, one of the first insertion part and the first clamping member is provided with a first through hole, and the other is provided with a first limiting protrusion that can pass through the first through hole; and / or, one of the second insertion part and the second clamping member is provided with a second through hole, and the other is provided with a second limiting protrusion that can pass through the second through hole.

[0016] More specifically, along the direction in which the first limiting protrusion is inserted into the first through hole, the longitudinal cross-sectional area of ​​the first limiting protrusion gradually decreases; along the direction in which the second limiting protrusion is inserted into the second through hole, the longitudinal cross-sectional area of ​​the second limiting protrusion gradually decreases.

[0017] Optionally, the indicating device further includes a first support bracket and a second support bracket, both of which are fixedly mounted on the hollow base. The first support bracket and the first clamping member can jointly clamp the first insertion part, and the second support bracket and the second clamping member can jointly clamp the second insertion part.

[0018] Optionally, the indicating device further includes a fixing member fixedly disposed in the hollow seat body, with the first clamping member and the second clamping member respectively disposed on opposite sides of the fixing member, and both capable of abutting against the fixing member.

[0019] Optionally, the indicator device also includes a protective cover, with an opening at the top of the hollow base and the protective cover positioned at the opening.

[0020] Optionally, the indicating device further includes a support base, which is fixedly connected to the hollow base, and the cross-sectional area of ​​the support base is larger than the cross-sectional area of ​​the hollow base.

[0021] The beneficial effects of this utility model are:

[0022] This invention proposes an indicator device. The connector includes a connecting part, a first plug-in part, and a second plug-in part. The connecting part connects to the indicator sign, and the first and second plug-in parts can be inserted into the hollow base. Compared with traditional welding or clamp fastening methods, this significantly improves the efficiency of installation and removal, and shortens the time required for the installation and removal of the indicator sign. After the first and second plug-in parts are inserted into the hollow base, a first clamping member abuts against the first plug-in part, and a second clamping member abuts against the second plug-in part. The abutment of the connector by the first and second clamping members secures the indicator sign to the hollow base, improving the convenience of high-altitude installation and removal operations. The fixing of the indicator sign to the hollow base eliminates the need for construction personnel to carry tools for high-altitude operations, avoiding the risk of tools falling and improving the safety of indicator sign installation and removal operations.

[0040] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1-7As shown, this utility model provides an indicating device, including an indicator sign 1, a hollow base 2, a connector 3, and a clamping assembly 4. The connector 3 includes a connecting portion 31, a first connector 32, and a second connector 33. The connecting portion 31 is connected to the indicator sign 1. The first connector 32 and the second connector 33 are both fixedly connected to the connecting portion 31 and can both be inserted into the hollow base 2. The clamping assembly 4 is disposed within the hollow base 2 and includes a first clamping member 41 and a second clamping member 42. At least one of the first clamping member 41 and the second clamping member 42 is movably connected to the hollow base 2, such that the first clamping member 41 can abut against the first connector 32, and the second clamping member 42 can abut against the second connector 33. In this embodiment, both the first connector 32 and the second connector 33 are plate-shaped structures.

[0045] The connecting part 31 connects to the sign 1, and the first insertion part 32 and the second insertion part 33 can be inserted into the hollow base 2. Compared with the existing technology that uses welding or clamping to fasten and disassemble the sign 1, this effectively shortens the time required for installing and disassembling the sign 1 and improves the efficiency of installation and disassembly. The sign 1 and the connecting part 31 can be fixedly connected to improve their overall integrity. The sign 1 and the connecting part 31 can also be detachably connected, requiring only the removal of the sign 1 from the connecting part 31 without adjusting the first clamping member 41 and / or the second clamping member 42, simplifying the installation and disassembly process of the sign 1. The detachable connection between the sign 1 and the connecting part 31 can improve the reusability of the insertion part 3. During installation and disassembly, only the sign 1 needs to be replaced, meaning that the insertion part 3 can be adapted to sign 1 of different specifications. Understandably, to facilitate the insertion of the first insertion part 32 and the second insertion part 33 into the hollow base 2, the hollow base 2 is provided with a first insertion slot and a second insertion slot at intervals on its wall surface. The first insertion part 32 can be inserted into the first insertion slot, and the second insertion part 33 can be inserted into the second insertion slot. The size of the first insertion slot can be slightly larger than the size of the first insertion part 32, and the size of the second insertion slot can be slightly larger than the size of the second insertion part 33, thereby facilitating the assembly and disassembly of the first insertion part 32 and the second insertion part 33, and reducing the machining accuracy requirements for the first insertion part 32 and the second insertion part 33.

[0046] After the first connector 32 and the second connector 33 are inserted into the hollow base 2, the first clamping member 41 abuts against the first connector 32, and the second clamping member 42 abuts against the second connector 33. The first clamping member 41 and the second clamping member 42 form a bidirectional clamping fit, improving the connection stability between the sign 1 and the hollow base 2. Furthermore, the sign 1 and the hollow base 2 are fixed by the abutting of the connector 3 by the first clamping member 41 and the second clamping member 42, greatly facilitating high-altitude assembly and disassembly operations. The fixing of the sign 1 and the hollow base 2 eliminates the need for construction personnel to carry tools for high-altitude operations, avoiding the risk of tools falling and improving the safety of assembly and disassembly operations.

[0047] In this embodiment, as Figure 1 and Figure 2 As shown, the indicating device also includes a support base 9, which is fixedly connected to the hollow base 2. The cross-sectional area of ​​the support base 9 is larger than that of the hollow base 2. The support base 9 is positioned below the hollow base 2, and its larger cross-sectional area enhances the overall structural stability of the indicating device and strengthens its anti-tipping effect.

[0048] Of the first clamping member 41 and the second clamping member 42, at least one can be slidably connected to the hollow base 2, so that the distance between the first clamping member 41 and the second clamping member 42 is adjustable, thereby realizing the clamping or loosening process of the first clamping member 41 and the second clamping member 42 on the plug-in member 3. In this embodiment, both the first clamping member 41 and the second clamping member 42 are slidably connected to the hollow base 2. Compared with only one of the first clamping member 41 and the second clamping member 42 being slidably connected to the hollow base 2, the clamping effect of both the first clamping member 41 and the second clamping member 42 on the plug-in member 3 is enhanced, thereby improving the fixing effect between the sign 1 and the hollow base 2, and also shortening the adjustment time of the distance between the first clamping member 41 and the second clamping member 42. When the first clamping member 41 and the second clamping member 42 slide towards each other, the first clamping member 41 moves away from the first insertion part 32, and the second clamping member 42 moves away from the second insertion part 33. The clamping assembly 4 does not have a clamping or limiting effect on the insertion member 3, and the insertion member 3 can be disassembled from the hollow base 2 to realize the disassembly process of the sign 1. When the first clamping member 41 and the second clamping member 42 slide away from each other, the first clamping member 41 moves closer to the first insertion part 32, and the second clamping member 42 moves closer to the second insertion part 33. The clamping assembly 4 can clamp the insertion member 3 to fix the sign 1 to the hollow base 2.

[0049] The sliding of the first clamping member 41 and the second clamping member 42 can be achieved by setting a slide rail inside the hollow base 2, allowing both the first clamping member 41 and the second clamping member 42 to slide along the slide rail. Setting the slide rail ensures that the first clamping member 41 and the second clamping member 42 slide along a specific trajectory, improving the sliding stability of the first clamping member 41 and the second clamping member 42. Figures 3-5 As shown, the sliding of the first clamping member 41 and the second clamping member 42 can also be achieved by setting a guide member 43. The guide member 43 is horizontally disposed through the hollow base 2. Both the first clamping member 41 and the second clamping member 42 are slidably connected to the guide member 43. When the first clamping member 41 and the second clamping member 42 slide in opposite directions along the guide member 43, the first clamping member 41 can abut against the first insertion part 32, and the second clamping member 42 can abut against the second insertion part 33. The guide member 43 can provide guidance for the sliding process of the first clamping member 41 and the second clamping member 42, while reducing the processing cost of the hollow base 2. The guide member 43 can be a guide rod.

[0050] In this embodiment, the clamping assembly 4 further includes an adjusting member 44, which is horizontally disposed through the hollow base 2. The first clamping member 41 and the second clamping member 42 are both threadedly connected to the adjusting member 44. Rotating the adjusting member 44 causes the first clamping member 41 and the second clamping member 42 to slide towards or away from each other along the guide member 43. The synergistic mechanism between the adjusting member 44 and the guide member 43 is similar to the working principle of a nut and screw pair. The guide member 43 prevents the first clamping member 41 and the second clamping member 42 from rotating when the adjusting member 44 rotates. With the adjusting member 44 installed, the first clamping member 41 and the second clamping member 42 can be moved closer or further apart simply by driving the adjusting member 44 to rotate, reducing the difficulty of adjusting the relative positions of the first clamping member 41 and the second clamping member 42.

[0051] The adjusting component 44 may include an adjusting knob 441 and a screw 442 fixedly connected. Both the first clamping component 41 and the second clamping component 42 have threaded holes that engage with the screw 442. The adjusting knob 441 is located at the end of the screw 442 that protrudes from the hollow base 2. The rotation of the adjusting component 44 can be manually driven. After climbing to a height, construction personnel can manually rotate the adjusting knob 441 to rotate the screw 442, thereby changing the position of the first clamping component 41 and the second clamping component 42. This process eliminates the need for construction personnel to carry tools to a height, avoiding the risk of tools falling and ensuring high construction safety. The rotation of the adjusting component 44 can also be achieved using a rotary drive device such as an electric motor. By switching the rotation direction of the rotary drive device, the clamping and releasing processes of the first clamping component 41 and the second clamping component 42 on the connector 3 can be realized, improving the intelligence level of the disassembly and assembly indicator 1.

[0052] To enable the first clamping member 41 and the second clamping member 42 to slide towards or away from each other along the guide member 43 when the adjusting member 44 rotates, the threads of the screw 442 near the first clamping member 41 and the second clamping member 42 can be machined in opposite directions, allowing them to slide in opposite directions. Alternatively, the threads near the first clamping member 41 and the second clamping member 42 can be machined in the same direction but with different pitches, resulting in different sliding speeds of the first clamping member 41 and the second clamping member 42 along the guide member 43, thereby enabling them to slide towards or away from each other.

[0053] In another embodiment, the sliding process of the first clamping member 41 and the second clamping member 42 along the guide member 43 can also be driven by a linear drive device such as a cylinder. Cylinders can be connected to the first clamping member 41 and the second clamping member 42 respectively, and through the extension and retraction of the cylinders, the first clamping member 41 and the second clamping member 42 can slide towards each other and away from each other along the guide member 43 respectively.

[0054] In other embodiments, the hollow base 2 may also be provided with a toothed groove, and at least one of the first clamping member 41 and the second clamping member 42 is provided with a gear that meshes with the toothed groove. The gear is connected to a rotary drive device such as an electric motor. By switching the drive direction of the rotary drive device, the first clamping member 41 and the second clamping member 42 can move towards or away from each other, which facilitates fixing the sign 1 to the hollow base 2 or removing the sign 1 from the hollow base 2.

[0055] Specifically, of the first insertion part 32 and the first clamping member 41, one is provided with a first through hole 321, and the other is provided with a first limiting protrusion 411 that can pass through the first through hole 321; and / or, of the second insertion part 33 and the second clamping member 42, one is provided with a second through hole 331, and the other is provided with a second limiting protrusion 421 that can pass through the second through hole 331. Providing the first limiting protrusion 411 and / or the second limiting protrusion 421 can improve the clamping effect of the clamping assembly 4 on the indicator 1, and enhance the connection stability between the indicator 1 and the hollow base 2. In this embodiment, as... Figures 5-7 As shown, the first insertion part 32 is provided with a first through hole 321, the first clamping member 41 is provided with a first limiting protrusion 411, the second insertion part 33 is provided with a second through hole 331, and the second clamping member 42 is provided with a second limiting protrusion 421. Through the above configuration, the limiting effect of the first clamping member 41 on the first insertion part 32 and the limiting effect of the second clamping member 42 on the second insertion part 33 are enhanced, avoiding the risk of overturning that may still exist after the clamping assembly 4 clamps the insertion part 3.

[0056] More specifically, along the direction in which the first limiting protrusion 411 is inserted into the first through hole 321, the longitudinal cross-sectional area of ​​the first limiting protrusion 411 gradually decreases; along the direction in which the second limiting protrusion 421 is inserted into the second through hole 331, the longitudinal cross-sectional area of ​​the second limiting protrusion 421 gradually decreases, thereby reducing the difficulty of inserting the first limiting protrusion 411 into the first through hole 321 and the second limiting protrusion 421 into the second through hole 331, and also reducing the machining accuracy requirements for the first through hole 321 and the second through hole 331. The first limiting protrusion 411 and the second limiting protrusion 421 can be frustum-shaped or conical. In other embodiments, to facilitate the insertion of the first limiting protrusion 411 into the first through hole 321, a chamfer can be machined on the side of the first limiting protrusion 411 near the first through hole 321, and the second limiting protrusion 421 can also undergo the same machining as the first limiting protrusion 411.

[0057] In this embodiment, the indicating device further includes a first supporting bracket 5 and a second supporting bracket 6. Both the first supporting bracket 5 and the second supporting bracket 6 are fixedly mounted on the hollow base 2. The first supporting bracket 5 and the first clamping member 41 can jointly clamp the first insertion part 32, and the second supporting bracket 6 and the second clamping member 42 can jointly clamp the second insertion part 33. The first supporting bracket 5 and the second supporting bracket 6 are respectively fixedly mounted at both ends of the hollow base 2. The first supporting bracket 5 and the second supporting bracket 6 can work together with the clamping assembly 4 to enhance the clamping and fixing effect on the first insertion part 32 and the second insertion part 33, thereby improving the connection stability between the indicator sign 1 and the hollow base 2. When the first supporting bracket 5 and the first clamping member 41 clamp the first insertion part 32 and the second supporting bracket 6 and the second clamping member 42 clamp the second insertion part 33, the external loads such as wind force on the indicator sign 1 can be transferred to the hollow base 2, avoiding stress concentration and other problems at the locations of the first insertion part 32 and the second insertion part 33.

[0058] Specifically, the first support bracket 5 has a third through hole 51, and the second support bracket 6 has a fourth through hole 61. When the first insertion part 32 and the second insertion part 33 are inserted into the hollow base 2, the first through hole 321, the second through hole 331, the third through hole 51, and the fourth through hole 61 are all axially aligned. When the first clamping member 41 and the second clamping member 42 move in opposite directions, the first limiting protrusion 411 can sequentially pass through the first through hole 321 and the third through hole 51, and the second limiting protrusion 421 can sequentially pass through the second through hole 331 and the fourth through hole 61. The third through hole 51 on the first support bracket 5 and the fourth through hole 61 on the second support bracket 6 can limit the farthest distance of the opposite movement of the first clamping member 41 and the second clamping member 42.

[0059] The indicating device may further include a fixing member 7 fixedly disposed within the hollow base 2. A first clamping member 41 and a second clamping member 42 are respectively disposed on opposite sides of the fixing member 7 and both can abut against the fixing member 7. When the first clamping member 41 and the second clamping member 42 move towards each other, they can abut against opposite sides of the fixing member 7 respectively. The fixing member 7 limits the minimum distance between the first clamping member 41 and the second clamping member 42, preventing collisions due to operational errors. In this embodiment, the fixing member 7 is disposed through the hollow base 2 along its axial direction, dividing the internal space of the hollow base 2 into two chambers of equal size.

[0060] In this embodiment, the indicating device also includes a protective cover plate 8. The top of the hollow base 2 has an opening, and the protective cover plate 8 is positioned at the opening. The protective cover plate 8 provides waterproofing and windproofing for the components housed within the hollow base 2, reducing the erosion of internal components by rain and wind, and helping to extend its service life. The protective cover plate 8 can be bolted to the top of the hollow base 2 or hinged. A first insertion interface 81 and a second insertion interface 82 can be provided on the side of the protective cover plate 8 near the indicator 1. The first insertion interface 81 communicates with a first insertion slot, and the second insertion interface 82 communicates with the second insertion slot. During installation, the first insertion part 32 can slide from top to bottom into the first insertion slot via the first insertion interface 81, and the second insertion part 33 can slide from top to bottom into the second insertion slot via the second insertion interface 82. The disassembly direction is opposite to the above directions. The opening at the top of the hollow base 2 allows the clamping assembly 4 to be positioned near the opening, facilitating regular maintenance of the internal components of the hollow base 2 by construction personnel.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
