Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, and in particular to a safety protection device for municipal road foundation pits. Background Technology

[0002] The installation of protective devices for municipal road foundation pits includes temporary measures such as warning signs and barriers, as well as permanent solutions such as quick-repair materials. Among these, barriers with warning signs are the most commonly used. These types of safety protection devices for municipal road foundation pits are generally as shown in the attached instruction manual. Figure 1 As shown, the fence includes a fence 01, with supporting feet 02 symmetrically fixed at the two bottom corners of the fence 01, and a warning sign 03 with the words "Strictly Prohibited from Crossing", "Municipal Government", and "No Crossing" fixed in the middle of the fence 01.

[0003] However, in the aforementioned existing technologies, the supporting legs 02 are often quite large to ensure stability during placement. This causes the supporting legs 02 to easily jam against each other during bulk stacking and transportation, increasing the overall space occupied and making transportation difficult. Furthermore, the warning signs on these fencing structures are generally custom-made, lacking flexibility. Changing the warning signs requires reprinting or even purchasing a new batch of devices.

[0004] Therefore, this application provides a safety protection device for municipal road foundation pits to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a safety protection device for municipal road foundation pits to solve the problems of existing municipal road foundation pit installation protection devices, such as the support feet abutting each other during stacking and transportation, which increases the overall space occupied, is not conducive to transportation and carrying, and the warning signs on them are not convenient to be flexibly changed according to needs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A safety protection device for a municipal road foundation pit includes a fence. Vertical support legs are symmetrically fixed at both ends of the bottom of the fence. Two receiving grooves are symmetrically opened on both sides of the support legs. A support foot that can be horizontally unfolded is hinged to the bottom end of the receiving groove. A limit plate is hinged to the middle of the receiving groove. The lower end of the limit plate abuts against the upper end surface of the horizontally unfolded support foot to form an abutment limit.

[0008] A warning sign is provided in the middle of the fence. The warning sign has a square opening in the middle. A warning plate that hangs down naturally is hinged to the top of the square opening. Transparent parts are symmetrically installed on both sides of the warning plate. A slot is provided in the warning plate between the two transparent parts.

[0009] A first magnetic block is fixed to the upper surface of the support leg after it is horizontally unfolded, and the first magnetic block is magnetically attracted to the inner wall of the receiving groove.

[0010] A second magnetic block is fixed on both sides of the limiting plate, and the second magnetic block is magnetically attracted to the inner wall of the receiving groove.

[0011] The limiting plate includes an upward flipped state and a downward flipped state, and the lower end of the limiting plate in the downward flipped state abuts against the upper end surface of the support foot after it is horizontally unfolded.

[0012] The top of the warning board is fixed with a connecting part, which is rotatably installed on the top of the square opening inside the warning sign.

[0013] The bottom of the warning board has an opening that connects to the bottom of the slot, and the slot is used to hold and fix the warning sign board.

[0014] The bottom end of the warning board in its naturally hanging state abuts against the bottom surface of the inner square opening of the warning sign.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the cooperation of the support legs, the receiving groove, the support feet and the limiting plate, the support feet can be stored at the bottom of the receiving groove, avoiding the problem of mutual contact when the device is stacked in batches. This facilitates the orderly stacking of the device, and the space occupied when stacking is smaller than that of the existing technology, making it convenient for transportation and carrying.

[0017] In the above solution, thanks to the combination of warning signs, warning boards, transparent parts, and card slots, the warning signs can be fixed in the card slots and displayed through the transparent parts. When the warning signs need to be replaced, the old warning signs in the card slots can be pulled out and replaced without reprinting or customizing new barriers, making it more flexible to use.

[0018] In summary, this device uses retractable legs, which reduces the space occupied when stacked, making it convenient for transportation and carrying. The warning label in the middle is also easy to replace, making it flexible in use and effective overall. Attached Figure Description

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0028] The following is a detailed description of a safety protection device for municipal road foundation pits provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0030] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0031] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0032] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, an embodiment of this utility model provides a safety protection device for a municipal road foundation pit, including a enclosure 1. Vertical support legs 2 are symmetrically fixed at both ends of the bottom of the enclosure 1. Two receiving grooves 3 are symmetrically opened on both sides of the support legs 2. Support feet 4 that can be horizontally unfolded are hinged to the bottom end of the receiving grooves 3. A first magnetic block 401 is fixed to the upper surface of the horizontally unfolded support feet 4, so that the support feet 4 can be erected and stored at the bottom of the receiving grooves 3. The first magnetic block 401 is magnetically attracted to the inner wall of the receiving grooves 3 to form a fixation.

[0034] A limiting plate 5 is hinged to the middle of the receiving groove 3. The lower end of the limiting plate 5 abuts against the upper surface of the horizontally unfolded support leg 4, forming abutment and limiting. Specifically, the limiting plate 5 has an upward flipped state and a downward flipped state. The lower end of the limiting plate 5 in the downward flipped state abuts against the upper surface of the horizontally unfolded support leg 4. Furthermore, a second magnetic block 501 is fixed on both sides of the limiting plate 5, and the second magnetic block 501 magnetically engages with the inner wall of the receiving groove 3. Therefore, when the limiting plate 5 is upright, it can be magnetically attracted to the inner wall of the top position of the receiving groove 3 by the second magnetic block 501 on one side, forming a fixed storage, leaving the bottom position of the receiving groove 3 open for the support foot 4 to be upright and stored. When the limiting plate 5 is hanging down, it can be magnetically attracted to the inner wall of the bottom position of the receiving groove 3 by the second magnetic block 501 on the other side, ensuring that the limiting plate 5 is vertically downward, and the lower end of the limiting plate 5 abuts against the upper end surface of the horizontally unfolded support foot 4 to form abutment and fixation, ensuring that the support foot 4 is in a horizontal state. In specific implementation, the magnetic force of the above-mentioned magnetic blocks is moderate, which can maintain a certain magnetic attraction force without causing a problem of difficulty in separation. The specific selection can be adjusted according to the needs of production, which will not be elaborated here.

[0035] Cooperate Figure 5 As shown, a warning sign 6 is provided in the middle of the enclosure 1. A square opening is provided in the middle of the warning sign 6. A warning plate 7 is hinged to the top of the square opening and hangs down naturally. Transparent parts 8 are symmetrically installed on both sides of the warning plate 7. The transparent parts 8 can be made of, but are not limited to, transparent acrylic sheets. A slot 9 is provided in the warning plate 7 between the two transparent parts 8.

[0036] The warning plate 7 has a connecting part 701 fixed to its top. The connecting part 701 is rotatably mounted to the top of the square opening inside the warning sign 6 via a mounting shaft, forming a hinged installation. The bottom end of the warning plate 7 has an opening communicating with the bottom of the slot 9, which is used to secure the warning sign. When the warning plate 7 is naturally hanging down, its bottom end abuts against the bottom surface of the square opening inside the warning sign 6. Therefore, when the warning plate 7 hangs down naturally, the bottom surface of the square opening inside the warning sign 6 blocks the bottom opening of the slot 9, improving the securing effect of the warning sign inside the slot 9.

[0037] The working principle provided by this utility model is that, when in use, the support leg 4 can be stored in the bottom of the receiving groove 3 or laid out horizontally, thereby avoiding the problem of mutual contact when the device is stacked in batches. This facilitates the orderly stacking of the device, and the space occupied when stacking is smaller than that of the prior art, making it convenient for transportation and carrying.

[0038] Meanwhile, the warning sign can be fixed in the slot 9 opened in the warning plate 7 inside the warning sign 6 through the middle of the fence 1, and can be displayed through the transparent parts 8 on both sides. When the warning sign needs to be replaced, the old warning sign can be pulled out of the slot 9 and replaced. There is no need to reprint or customize a new fence, making it more flexible to use.

[0039] In summary, this device uses retractable legs, which reduces the space occupied when stacked, making it convenient for transportation and carrying. The warning label in the middle is also easy to replace, making it flexible in use and effective overall.

[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
