Description

Technical Field

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

[0002] Currently, during emergency power repair work, on-site personnel are equipped with specialized protective gear and electrical tools. These tools, such as warning signs, are placed on-site to alert nearby personnel, ensuring the smooth progress of repairs and the safety of those in the vicinity. Generally, warning signs consist of a sign and a support. The support is typically T-shaped or V-shaped, and for ease of carrying, handling, and storage, the support is often foldable, as illustrated by patents CN213424423U (disclosed as a portable, foldable warning sign for power construction) and CN210925248U (disclosed as a foldable safety sign).

[0003] However, existing folding warning signs have complex structures, high manufacturing costs, heavy weight, and are difficult to handle. Moreover, they are still relatively large in size after being folded, and take up a lot of space when stored. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an electric power indicator device that is simple in structure, lightweight and easy to transport, occupies little storage space, and is also low in cost.

[0005] This utility model embodiment provides an electric power sign device, which includes:

[0006] A frame having an opening structure extending along a first direction, and the frame having downward-facing cavities on opposite sides along a second direction.

[0007] A signboard, which is located in the opening structure and connected to the frame;

[0008] The folding assembly has two components, which are respectively located on opposite sides of the frame along the second direction. Each folding assembly includes a first link and a second link that are hinged to each other. The second link has two slots that are spaced apart along the first direction and extend through the frame along the second direction. The folding assembly has a use state and a storage state.

[0009] Cap;

[0010] When the folding assembly is in use, the first connecting rod and the second connecting rod form an acute angle, each of the first connecting rods is located within the cavity, each of the second connecting rods extends along a first direction, the frame abuts against the upper surfaces of the two second connecting rods, and the cover extends along a second direction and engages with the slots on the two second connecting rods; when the folding assembly is in storage, the first connecting rod and the second connecting rod extend along the vertical direction and are stored within the cavity, and the cover closes to the two opening structures of the frame, with the first direction, the second direction, and the vertical direction being perpendicular to each other.

[0011] The power sign device according to the embodiment of this utility model has at least the following beneficial effects: When using the power sign device, the sign is set at the opening structure of the frame, which can provide a safety warning at the power construction site. By rotating the first link and the second link relative to each other, the first link is located inside the cavity, and the second link is located outside the cavity and abuts against the ground. The first link and the second link form a certain acute angle, so that the frame can abut against the upper surface of the two second links in an inclined state, which prevents the frame from easily tipping over in the first direction. Moreover, the cover can be perpendicularly connected to the two second links and engaged with the two slots on the two second links. This not only prevents the cover from being easily lost, but also prevents the second link from rotating on the horizontal plane, which would reduce its support effect on the frame.

[0012] When it is necessary to move or store the power indicator device, the relative rotation between the first and second links allows the first and second links to retract into the cavity of the frame. The two openings of the frame are then sealed with caps to prevent the first and second links from easily coming out of the cavity, thus facilitating handling and preventing the first and second links from being easily lost.

[0013] This structure simplifies the electric power sign device, making it lighter and easier to handle, while also reducing manufacturing costs. Furthermore, by housing the folding components within the cavity, it facilitates transportation and reduces the space occupied by the electric power sign device during storage.

[0014] In some embodiments of this utility model, the frame is provided with slots on opposite sides along the second direction. The slots are located on one side of the frame along the first direction and communicate with the cavity. When the folding assembly is in use, the second connecting rod engages with the slots, and the two sides of the second connecting rod along the second direction respectively contact the sidewalls of the slots.

[0015] In some embodiments of this utility model, when the folding assembly is in use, the upper surface of the second connecting rod is in contact with the inner upper wall of the bayonet.

[0016] In some embodiments of this utility model, when the folding assembly is in the storage state, the cover closes to the two opening structures and the two bayonet slots.

[0017] In some embodiments of this utility model, the first connecting rod and the second connecting rod are connected by a pivot.

[0018] In some embodiments of this utility model, the first connecting rod and the second connecting rod are solid rods.

[0019] In some embodiments of this utility model, both the first connecting rod and the second connecting rod are square rods, and when the folding assembly is in the storage state, both the first connecting rod and the second connecting rod are in sliding contact with the wall of the cavity.

[0020] In some embodiments of this utility model, the frame is in the shape of a square ring.

[0021] In some embodiments of this utility model, the frame is a hollow structure.

[0022] In some embodiments of this utility model, the lower part of the frame is provided with at least one bar magnet, the bar magnet is located between the two cavities, and the bar magnet is configured to magnetically connect with the cover.

[0023] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description, claims, and drawings.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] 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.

[0034] 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.

[0035] The following is for reference. Figures 1 to 7 This invention describes an electric power sign device provided according to an embodiment of the present invention.

[0036] like Figures 1 to 7 As shown, the power sign device according to this embodiment of the utility model can be placed in power construction sites to serve as a reminder and warning to surrounding personnel. This power sign device has the advantages of simple structure, ingenious design, practicality, reliability, and easy transport. Furthermore, it occupies little storage space and has low manufacturing costs during warehousing.

[0037] The power sign device has a first direction, a second direction, and a vertical direction, wherein 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 front-back direction, and the second direction is the left-right direction.

[0038] The structure of the power sign device includes a frame 200, a sign 100, a folding assembly 300, and a cover 400.

[0039] The frame 200 has an opening structure that extends along a first direction, and the shape of the opening structure matches the shape of the sign 100. The frame 200 has two cavities 220, each with a downward-facing opening. These two cavities 220 are located on opposite sides of the frame 200 along a second direction, with the opening structure located between them. It is understood that the function of the cavity 220 is to accommodate the folding assembly 300. The shape and size of the cavity 220 are determined based on the specific characteristics of the folding assembly 300 and are not specifically limited here.

[0040] The sign 100 is located within the opening structure of the frame 200, and is fixedly connected to the frame 200. Understandably, the signage on the sign 100 serves a reminder and warning function. The sign 100 can be square-shaped, in which case the opening structure is square. The sign 100 can be fixed to the frame 200 by welding, screwing, adhesive bonding, or magnetic attraction.

[0041] Two folding assemblies 300 are provided, and the two folding assemblies 300 are respectively arranged on opposite sides of the frame 200 along the second direction. Each folding assembly 300 includes a first link 310 and a second link 320, wherein the first link 310 and the second link 320 are hinged to each other, and the hinge axis between the first link 310 and the second link 320 extends along the second direction. Specifically, the first link 310 and the second link 320 are connected by a pivot 330. The first link 310 and the second link 320 are capable of relative rotation to achieve the folding or unfolding of the folding assembly 300.

[0042] In this embodiment, one end of the first connecting rod 310 is provided with two first connecting ears arranged at intervals along the second direction, and one end of the second connecting rod 320 is provided with a second connecting ear at the middle position. Both the first and second connecting ears have connecting holes, and the rotating shaft 330 passes through the first and second connecting ears, with the second connecting ear located between the two first connecting ears. Of course, it is not ruled out that the first connecting rod 310 and the second connecting rod 320 are connected by a hinge.

[0043] Furthermore, each second link 320 is provided with a slot 321, and there are two slots 321. The two slots 321 are arranged at intervals along the first direction, and the slots 321 extend through each other along the second direction.

[0044] The folding component 300 has a used state and a folded state. For example... Figures 1 to 4 As shown, when the folding assembly 300 is in use, the first link 310 and the second link 320 form a certain acute angle, the specific value of which can be 80°, 75°, or 60°, etc. Moreover, each first link 310 is located inside the cavity 220, the hinge end between the first link 310 and the second link 320 is located outside the cavity 220, the second link 320 is also located outside the cavity 220, each second link 320 extends along a first direction, the lower surface of the second link 320 is in direct contact with the ground, the frame 200 is inclined and abuts against the upper surface of the two second links 320, and the frame 200 is supported by the two second links 320.

[0045] The cover 400 extends along the second direction and engages with two slots 321 on the two second connecting rods 320. It is understood that the cover 400 has two long sidewalls and two short sidewalls, one long sidewall engaging with one slot 321 of the two second connecting rods 320, and the other long sidewall engaging with the other slot 321 of the two second connecting rods 320.

[0046] like Figures 5 to 7 As shown, when the folding assembly 300 is in the retracted state, the first link 310 and the second link 320 in the folding assembly 300 extend in the vertical direction, that is, the length direction of the first link 310 and the length direction of the second link 320 coincide, and the first link 310 and the second link 320 can be stored in the cavity 220. The cover 400 covers the two opening structures of the frame 200, and the cover 400 is detachably connected to the frame 200. At this time, due to the blocking effect of the cover 400, the first link 310 and the second link 320 can be prevented from easily detaching from the cavity 220.

[0047] In some embodiments, the first link 310 and the second link 320 are solid rods, which can strongly support the frame 200 and are not easily deformed. Furthermore, both the first link 310 and the second link 320 are square rods, and the cavity 220 is a square prism-shaped cavity, allowing both the first link 310 and the second link 320 to slide smoothly along the wall of the cavity 220. The corners of the first link 310 and the second link 320 can be rounded. When the folding assembly 300 is in the stowed state, both the first link 310 and the second link 320 slide in contact with the wall of the cavity 220, preventing the first link 310 and the second link 320 from shaking and generating noise within the cavity 220.

[0048] Of course, it is not excluded that in other embodiments, the cross-sectional shape of the first link 310 and the second link 320 is semi-circular.

[0049] In some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the frame 200 is provided with two bayonets 210, which are located on opposite sides of the frame 200 along the second direction and on one side of the frame 200 along the first direction. The bayonets 210 are in communication with the cavity 220. The shape of the bayonets 210 is adapted to the shape of the second connecting rod 320.

[0050] When the folding assembly 300 is in use, the second link 320 is located on the rear side of the frame 200, and the latch 210 is formed on the rear side of the frame 200. Moreover, the second link 320 engages with the latch 210, and the two sides of the second link 320 along the second direction contact the side walls of the latch 210 respectively. The second link 320 is limited by the two side walls of the latch 210, preventing the second link 320 from easily rotating relative to the frame 200 on the horizontal plane and causing the frame 200 to tip over.

[0051] In this embodiment, when the frame 200 is in a vertical state, the inner upper wall of the latch 210 is inclined. Therefore, when the folding assembly 300 is in use, the upper surface of the second link 320 is in close contact with the inner upper wall of the latch 210, which increases the contact area between the frame 200 and the second link 320, allowing the second link 320 to better support the frame 200.

[0052] Of course, it is not excluded that in other embodiments, when the frame 200 is in a vertical state, the inner upper wall surface of the bayonet 210 is a horizontal plane.

[0053] When the folding assembly 300 is in the stowed state, the cover 400 can simultaneously close the two opening structures and the two latches 210, so that the first link 310 and the second link 320 inside the cavity 220 can be well protected, preventing dust and other debris from entering the cavity 220 during storage. The cover 400 is rectangular.

[0054] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, the frame 200 is in the shape of a square ring. Furthermore, the frame 200 is a hollow structure. Specifically, the frame 200 is formed by four vertically connected connecting rods, which are hollow square rods. This design reduces the weight of the frame 200, thereby reducing the pressure exerted by the frame 200 on the second connecting rod 320. It also saves materials and reduces the intensity of manual handling.

[0055] Of course, it is not excluded that in other embodiments, the frame 200 may be H-shaped as a whole.

[0056] In some embodiments, the lower part of the frame 200 is provided with at least one bar magnet, which is located between the two cavities 220 and is configured to magnetically connect with the cover 400. The bar magnet can be fixed to the lower part of the frame 200 by screws, and the length of the bar magnet can extend along a second direction. The bar magnet can directly apply a magnetic connection to the cover 400. Of course, the cover 400 can be provided with a corresponding iron sheet for magnetic attraction with the bar magnet.

[0057] This configuration allows the cover 400 to be detachably connected to the frame 200, and also increases the lower weight of the frame 200, lowering its center of gravity and thus improving the stability of the frame 200 when the power sign device is in use.

[0058] In the power sign device provided in this embodiment of the utility model, when the power sign device is used, the sign 100 is set at the opening structure of the frame 200, which can provide a safety warning at the power construction site. By rotating the first connecting rod 310 and the second connecting rod 320 relative to each other, the first connecting rod 310 is located inside the cavity 220, and the second connecting rod 320 is located outside the cavity 220 and abuts against the ground. The first connecting rod 310 and the second connecting rod 320 form a certain acute angle, so that the frame 200 can abut against the upper surface of the two second connecting rods 320 in an inclined state, which prevents the frame 200 from easily tipping over in the first direction. Moreover, the cover 400 can be perpendicularly connected to the two second connecting rods 320 and engaged with the two slots 321 on the two second connecting rods 320. This not only prevents the cover 400 from being easily lost, but also prevents the second connecting rods 320 from rotating on the horizontal plane, which would reduce their supporting effect on the frame 200.

[0059] When it is necessary to move or store the power indicator device, the relative rotation between the first link 310 and the second link 320 allows the first link 310 and the second link 320 to retract into the cavity 220 of the frame 200. The cover 400 closes the two openings of the frame 200, preventing the first link 310 and the second link 320 from easily coming out of the cavity 220, thus facilitating handling and preventing the first link 310 and the second link 320 from being easily lost.

[0060] This structure simplifies the electric power sign device, making it lighter and easier to handle, while also reducing manufacturing costs. Furthermore, by housing the folding component 300 within the cavity 220, transportation is facilitated, and the space occupied by the electric power sign device during storage is reduced.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
