Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to a portable power identification device. Background Technology

[0002] During power construction and maintenance, workers typically install power construction signs at the construction site to serve as reminders and warnings, thereby improving the safety of the work. Existing power construction signs are basically composed of the sign itself and a supporting frame. To improve the stability of the sign during placement, the bottom of the supporting frame must have a sufficiently large contact area with the ground. After the construction work is completed, the power construction signs need to be removed. Due to their large size, they occupy a lot of space during storage, making them inconvenient to transport and store. Therefore, some foldable power construction signs have appeared on the market. However, existing foldable power construction signs have complex structures, are heavy, inconvenient to move, and are also costly. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a portable power identification device that is simple in structure, lightweight, easy to carry and transport, occupies little space when stored, and is low in cost.

[0004] This utility model embodiment provides a portable power identification device, which includes:

[0005] A frame having a mounting opening extending along a second direction, the frame having cavities and locking holes on opposite sides along a first direction, the openings of the cavities being open downwards and communicating with the locking holes;

[0006] A signboard is installed inside the mounting opening and connected to the frame;

[0007] The support leg has two parts, which are respectively located on opposite sides of the frame along the first direction. The support leg includes a first rod, a second rod, and a third rod that are hinged sequentially along the vertical direction. The first rod is slidably connected to the wall of the cavity. The support leg has a storage state and a use state.

[0008] The locking element is provided in two parts, each corresponding to one of the two locking holes;

[0009] When the support leg is in the retracted state, the first rod, the second rod, and the third rod are configured to be sequentially spliced ​​together in the vertical direction and housed within the cavity. When the support leg is in the use state, the first rod, the second rod, and the third rod are configured to extend out of the cavity and together form a triangular structure for supporting the frame. The locking member is configured to engage with the locking hole to lock the upper end of the first rod to the frame, with the first direction, the second direction, and the vertical direction being perpendicular to each other.

[0010] The portable power identification device according to the present utility model has at least the following beneficial effects: when the portable power identification device is used at a power construction site, the first pole, the second pole, and the third pole extend out of the cavity and are fixed to the frame by the cooperation of the locking member and the locking hole. Moreover, the second pole and the third pole are bent relative to their hinge points so that the first pole, the second pole, and the third pole together form a stable triangular structure, so that the frame and the sign can maintain a stable state under the support of the support legs, and play a reminder and warning role.

[0011] When the portable power identification device needs to be moved or stored, the second and third rods are bent in the opposite direction to disassemble the triangular structure, so that the first, second, and third rods can be sequentially spliced ​​in the vertical direction and moved upward into the cavity to hide the support legs. This makes it convenient to carry and move the portable power identification device and reduces the space occupied by the portable power identification device during storage. Moreover, the portable power identification device has a simple structure, is lightweight, and has a low cost.

[0013] In some embodiments of this utility model, the frame is tilted when the support leg is in use.

[0014] In some embodiments of this utility model, the first rod body is provided with a latch on one side along the second direction. When the support leg is in use, the end of the third rod body away from the second rod body is configured to be able to be latched into the latch to support the first rod body.

[0015] In some embodiments of this utility model, the frame is provided with locking holes on opposite sides along the first direction. The locking holes are located above the locking holes. When the support leg is in the retracted state, the locking member is configured to engage with the locking holes to lock the first rod body and the frame.

[0029] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The following is for reference. Figures 1 to 5 This invention describes a portable power identification device provided according to an embodiment of the present invention.

[0032] like Figures 1 to 5 As shown, the portable power identification device according to the embodiment of this utility model has the advantages of simple structure, light weight, easy to carry and transport, small space occupation during storage and low manufacturing cost, and can be applied to power construction and maintenance sites.

[0033] The portable power identification device has a first direction, a second direction, and a vertical direction. The first direction is perpendicular to both the second direction and the vertical direction, and the second direction is perpendicular to the vertical direction. In this embodiment, it is assumed that the first direction is the left-right direction, and the second direction is the front-back direction.

[0034] The portable power identification device includes a frame 200, an identification plate 100, a support leg 300, and a locking element 400.

[0035] The frame 200 has a mounting opening that extends along a second direction. The frame 200 also includes a cavity 220 and a locking hole 230, with the locking hole 230 communicating with the cavity 220. Specifically, there are two cavities 220, located on opposite sides of the frame 200 along a first direction, each cavity 220 having a downward-facing opening. Similarly, there are two locking holes 230, located on opposite sides of the frame 200 along the first direction. It can be understood that the locking holes 230 can be located on the front, back, or sides of the frame 200. In this embodiment, locking holes 230 are provided on both the left and right sides of the frame 200, and are located at the lower part of the frame 200.

[0036] The sign 100 is disposed within the mounting opening of the frame 200, the sign 100 is adapted to the mounting opening, and the sign 100 is fixedly connected to the frame 200. It is understood that the sign 100 has a sign or warning on its front and / or back to remind or warn people. The sign 100 can be fixed to the frame 200 by bolting or welding. In this embodiment, the frame 200 can be made of metal such as iron. The frame 200 is formed by four metal rods vertically connected, making the mounting opening square, and the sign 100 square in shape.

[0037] Two support legs 300 are provided, and the two support legs 300 are respectively arranged on opposite sides of the frame 200 along the first direction. The two support legs 300 are respectively arranged corresponding to the two cavities 220. Specifically, the structure of the support leg 300 includes a first rod 310, a second rod 320, and a third rod 330. The first rod 310, the second rod 320, and the third rod 330 are hinged sequentially along the vertical direction of the frame 200. The first rod 310 is slidably connected to the wall of the cavity 220, so that the first rod 310 can move smoothly up and down along the wall of the cavity 220. This allows the support leg 300 to be retracted into the cavity 220 or extended out of the cavity 220. Therefore, the support leg 300 has a storage state and a use state.

[0038] In this embodiment, the first rod 310 and the second rod 320 are connected by a hinge 500, and the second rod 320 and the third rod 330 are connected by a hinge 500. Furthermore, the rotation axes of all the hinges 500 extend along a first direction. The second rod 320 can rotate clockwise or counterclockwise relative to the first rod 310 about the axis of rotation of the hinge 500 between them, and the third rod 330 can rotate clockwise or counterclockwise relative to the second rod 320 about the axis of rotation of the hinge 500 between them. The second rod 320 and the third rod 330 are square rods. The cross-sectional shape of the first rod 310 is square. The support leg 300 is made of metal such as iron.

[0039] Of course, it is not excluded that in other embodiments, the first rod 310 and the second rod 320 are connected by a hinge shaft, and the second rod 320 and the third rod 330 are also connected by a hinge shaft. The first rod 310, the second rod 320 and the third rod 330 can also be rods of other shapes.

[0040] Two locking members 400 are provided, and the two locking members 400 are respectively provided with two locking holes 230. The locking members 400 can cooperate with the locking holes 230 to lock the first rod 310 on the frame 200 when the second rod 320 and the third rod 330 are fully extended out of the cavity 220, so that the first rod 310 is fixed relative to the frame 200.

[0041] In some embodiments, the locking member 400 is disposed at the upper end of the first rod 310, and the locking member 400 is a pop-out post structure. It is understood that the pop-out post structure is prior art, and the pop-out post structure basically includes a spring and a locking post. The spring is disposed within the first rod 310, with one end connected to the first rod 310 and the other end connected to the locking post. The first rod 310 has a through hole for the locking post to enter and exit the through hole. When the first rod 310 is housed within the cavity 220, the pop-out post structure is in a compressed state, abutting against the wall of the cavity 220. When the first rod 310 moves downward relative to the frame 200 to an appropriate position, the pop-out post structure can engage with the locking hole 230 to lock the first rod 310 onto the frame 200. At this time, the locking hole 230 can be a circular hole.

[0042] In other embodiments, the locking element 400 is a locking bolt, which is disposed outside the cavity 220 of the frame 200 and configured to abut against the first rod 310. In this case, the locking hole 230 is a threaded hole, allowing the locking bolt to be screwed in or out of the locking hole 230. It is understood that when the first rod 310 moves downward relative to the frame 200 to an appropriate position, the locking bolt is screwed into the locking hole 230 and tightly abuts against the outer wall surface of the first rod 310, causing the locking bolt to exert a tightening effect on the first rod 310, thereby ensuring that the first rod 310 is firmly fixed relative to the frame 200. One end of the locking bolt may be provided with a quincunx handle.

[0043] When the support leg 300 is in the retracted state, the first rod 310, the second rod 320, and the third rod 330 are configured to be sequentially spliced ​​along the vertical direction. At this time, the first rod 310, the second rod 320, and the third rod 330 are combined to form a long rod, which can be completely stored in the cavity 220 of the frame 200. This makes it convenient for staff to carry and transport the portable power identification device. Moreover, after the support leg 300 is retracted into the cavity 220, the volume of the portable power identification device becomes smaller, and it occupies less space during transportation and storage, which helps to reduce transportation and storage costs.

[0044] When the support leg 300 is in use, the first rod 310, the second rod 320, and the third rod 330 are configured to extend outside the cavity 220. At this time, the second rod 320 and the third rod 330 are completely outside the cavity 220, while the first rod 310 is partially inside the cavity 220. The first rod 310, the second rod 320, and the third rod 330 together form a triangular structure for supporting the frame 200. Simultaneously, the locking member 400 is configured to engage with the locking hole 230 to lock the upper end of the first rod 310 to the frame 200. It is understood that after forming the triangular structure, the second rod 320 is in direct contact with the ground, and the third rod 330 is located above the second rod 320. The second rod 320 and the third rod 330 together provide favorable support to the first rod 310, ensuring a stable state for both the first rod 310 and the frame 200.

[0045] In this embodiment, as Figures 1 to 3 As shown, when the support leg 300 is in use, the frame 200 is tilted. It can be understood that if a sign is displayed on the front of the sign 100, then when the portable power sign is in use, the upper part of the frame 200 is tilted backward, causing the center of gravity of the frame 200 to shift backward. Under the support of the triangular structure formed by the first rod 310, the second rod 320, and the third rod 330, the frame 200 is less likely to tip over in the forward or backward direction, improving the stability of the portable power sign when placed on the ground.

[0046] In this embodiment, as Figures 1 to 3 , Figure 5 As shown, the first rod 310 has a latch 311 on one side along the second direction. Specifically, the latch 311 is recessed on one side of the first rod 310 along the second direction. In this embodiment, the upper end of the frame 200 is tilted backward, the lower end of the frame 200 is tilted forward, and the latch 311 is located on the rear side of the first rod 310, with the latch 311 open to the rear.

[0047] When the support leg 300 is in use, the end of the third rod 330 away from the second rod 320 is configured to engage with the latch 311 to support the first rod 310. At this time, the end of the third rod 330 away from the second rod 320 can abut against the wall of the latch 311, preventing the third rod 330 from easily falling down relative to the first rod 310. This ensures that the triangular structure formed by the first rod 310, the second rod 320 and the third rod 330 is more stable, and keeps the portable power identification device in a stable state.

[0048] When the support leg 300 needs to be retracted, force can be applied to the third rod 330 to drive it to swing upward relative to the latch 311, thereby releasing the latching action between the third rod 330 and the first rod 310, and splicing the first rod 310, the second rod 320 and the third rod 330 into a long rod to retract the support leg 300 into the cavity 220.

[0049] In some embodiments, as Figures 1 to 4 As shown, the frame 200 is provided with two locking holes 210, which are located on opposite sides of the frame 200 along the first direction and are positioned above the locking hole 230. When the support leg 300 is in the retracted state, the locking member 400 is configured to engage with the locking hole 210 to lock the first rod 310 to the frame 200.

[0050] Understandably, the locking hole 210 can be located on the front, rear, or left / right sides of the frame 200. When the locking member 400 is a pop-out post structure, the pop-out post structure can engage with the locking hole 210, so that the first rod 310 is fixed relative to the frame 200 when the support leg 300 is fully retracted into the cavity 220, preventing the support leg 300 from easily protruding from the cavity 220 when transporting the portable power identification device, thus avoiding adverse effects on people and transport operations. When the locking member 400 is a locking bolt, the locking hole 210 is a screw hole, and the locking bolt can be screwed into or out of the locking hole 210, applying a tightening effect to the first rod 310 retracted into the cavity 220.

[0051] In some embodiments, when the locking member 400 is a locking bolt, the first rod 310 is provided with a connecting hole, which is a threaded hole. In this case, the locking hole 210 and the locking hole 230 can be smooth through holes or threaded holes, and the locking bolt is configured to be threadedly connected to the connecting hole. It is understood that when the first rod 310 is fully retracted into the cavity 220, the connecting hole and the locking hole 210 are connected, and the locking bolt can pass through the locking hole 210 and be threadedly connected to the connecting hole, thus fixing the locking bolt to the first rod 310. When the first rod 310 partially extends out of the cavity 220, the connecting hole and the locking hole 230 are connected, and the locking bolt can pass through the locking hole 230 and be threadedly connected to the connecting hole, thus fixing the locking bolt to the first rod 310.

[0052] In this embodiment, the first rod 310, the second rod 320, and the third rod 330 are all solid structures, increasing the weight of the support leg 300, while the frame 200 can be a hollow structure, reducing its weight. Therefore, when the portable power identification device is in use, its center of gravity shifts downward, thereby improving its stability and making it less prone to tipping over.

[0053] Of course, it is not excluded that in other embodiments, at least one of the first rod 310, the second rod 320 and the third rod 330 may be a hollow structure.

[0054] When workers need to use this portable power sign device at a power construction site, the first pole 310, the second pole 320, and the third pole 330 extend from the cavity 220 of the frame 200. The locking element 400 and the locking hole 230 work together to fix the upper ends of the two first poles 310 to the frame 200. Furthermore, the second pole 320 and the third pole 330 are bent relative to their hinge points so that the first poles 310, the second pole 320, and the third pole 330 together form a stable triangular structure. This allows the frame 200 and the sign 100 to remain stable under the support of the two support legs 300, and serves to provide reminders and warnings to people.

[0055] When staff need to move or store the portable power identification device, the second rod 320 and the third rod 330 are bent in the opposite direction to disassemble the triangular structure. This allows the first rod 310, the second rod 320, and the third rod 330 to be sequentially assembled vertically and moved upwards and retracted into the cavity 220 of the frame 200, thus concealing the two support legs 300. This design facilitates the carrying and transport of the portable power identification device and reduces the space it occupies during storage. Furthermore, the portable power identification device has a simple overall structure, is lightweight, and has a low cost.
