Moreover, by setting a weakened portion on the two side walls of the insert, the stability of the connection between the two adjacent guardrails can be improved. The above setting can solve the problem of a traditional temporary engineering protection device which uses bolts for connection during use, is cumbersome and inconvenient to operate, and when the guardrail needs to be disassembled, the bolts need to be unscrewed and stored one by one. However, the bolts are easily lost during storage, which affects the next use.

[0028] The following is a detailed description of a temporary engineering protection device provided by the present utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present utility model.

[0029] It should be noted that the references to "one embodiment", "an embodiment", "an exemplary embodiment", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

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

[0031] It is to be understood that the meanings of “on,” “over,” and “above” in the present utility model should be interpreted in the broadest manner, so that “on” not only means “directly on” something but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” not only means “on” or “above” something but also includes the meaning of being “on” or “above” something with no intervening features or layers.

[0032] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0033] like Figures 1 to 5 As shown, the new embodiment of the utility model provides a temporary engineering protection device, including a guardrail 1, a left side plate 2 and a right side plate 3, the left side plate 2 and the right side plate 3 are respectively fixedly connected to the left and right sides of the guardrail 1; a limiting component, the limiting component is used to fix two adjacent guardrails 1, and the limiting components are respectively connected to the left side plate 2 and the right side plate 3. In the present application, by setting the limiting component, the two adjacent guardrails 1 can be fixedly connected, avoiding the use of bolts for fixing, and the operation is simple and convenient, and there is no need to consider the problem of bolt loss during disassembly.

[0034] In this embodiment, if Figure 2 As shown, the limiting assembly includes an insert piece 4 fixedly connected to the end of the right side plate 3 away from the left side plate 2, and a slot 5 adapted to the shape of the insert piece 4 is opened on the top of the left side plate 2. When the user connects two adjacent guardrails 1, he holds the right side plate 3 of a guardrail 1 and inserts the insert piece 4 into the slot 5 from top to bottom. Since the inclined arc concave inward in the middle of the insert piece 4 and the overall wavy curved surface arc are set to adapt to the contour of the wavy curved surface structure of the card slot 7, the slot 5 cavity is slightly larger than the insert piece 4, so that when the insert piece 4 is inserted into the slot 5, a covering effect is formed on the insert piece 4, and then a lateral limit is performed on the two connected guardrails 1, so that the two adjacent guardrails 1 are fixedly connected, and the connection method is simple and convenient.

[0035] In one implementation of this embodiment, Figure 3As shown, the two side walls of the plug 4 are fixedly connected with a clamping strip 6 at one end away from the right side plate 3, and a clamping slot 7 matching the shape of the clamping strip 6 is provided on the top of the left side plate 2. A weakened portion 8 is provided on the two side walls of the plug 4. The weakened portions 8 provided on the two side walls of the plug 4 make the plug 4 thinner at this location and easy to deform. Therefore, such a configuration makes it easier for the plug 4 to deform at the position of the weakened portion 8 under the action of external force. Under the action of elastic force, the weakened portion 8 is deformed and concave inward, so that the clamping strip 6 is clamped in the clamping slot 7. Under the action of elastic force, the clamping strip 6 is tightly attached to the clamping slot 7, thereby increasing the friction between them, so that the plug 4 is limited in the slot 5 and cannot shake back and forth, thereby improving the stability of the device.

[0036] In this embodiment, if Figure 4 and Figure 5 As shown, both side walls of the left side plate 2 are provided with a corrugated surface 10, and both side walls of the right side plate 3 are provided with a corrugated surface 2 9 that matches the shape of the corrugated surface 10. The inwardly concave inclined arc in the middle of the corrugated surface 10 and the overall curvature of the corrugated surface are set to adapt to the contour of the corrugated surface structure of the corrugated surface 2 9, so that when the guardrail 1 is stacked, the corrugated surface 10 fits with the corrugated surface 2 9, thereby realizing the stacking of the guardrail 1 and facilitating the subsequent transportation. Moreover, by setting the curved surface structure, when the guardrail 1 is stacked, the guardrail 1 can be slid and aligned with the help of the curved surface structure, making the stacking simple and convenient.

[0037] Both side walls of the left side panel 2 are provided with curved grooves 11 that are compatible with the insert 4 and the card strip 6. The curved groove 11 is an integrated structure and is divided into two sections. The section close to the guardrail 1 is compatible with the shape of the insert 4, and the other section is compatible with the shape of the card strip 6. When the user stacks the guardrails 1 together, the side walls of the insert 4 and the card strip 6 fit with the curved grooves 11 opened on the two side walls of the left side panel 2. The left side panel 2 and the right side panel 3 are stacked with the cooperation of the corrugated surface 10 and the corrugated surface 2 9. The set insert 4 and the left side panel 2 can be further stacked, so that the two guardrails 1 can be better and more stably stacked and stored.

[0038] When the user wants to remove the guardrail 1 and stack it up, the operator can then pick up the right side plate 3 of the other guardrail 1 that needs to be fixedly connected to the guardrail 1, and insert the insert strip into the slot 5 from top to bottom. The weakened portion 8 of the insert strip 4 becomes thinner, which is more likely to deform at the position of the weakened portion 8. Under the action of the elastic force, the weakened portion 8 deforms and concaves inwardly, so that the card strip 6 is clamped in the card slot 7, and under the action of the elastic force, the card strip 6 is tightly attached to the card slot 7, increasing the friction between them, so that the insert strip 4 is limited in the slot 5 and cannot swing back and forth, thereby improving the stability of the device. When the guardrail 1 needs to be disassembled and stacked, the guardrail 1 is pulled out of the slot 5 in turn, and then the guardrail 1 is placed horizontally. The left side plate 2 and the right side plate 3 are stacked under the cooperation of the corrugated surface 10 and the corrugated surface 29. The set insert strip 4 and the left side plate 2 can be further stacked, so that the guardrail 1 can be stacked better and more stably, which is convenient for later transportation.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the following preferred embodiments of the present invention, and the present invention can be fully understood by those skilled in the art without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
