[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Existing quick-installation protective devices for municipal construction are generally designed as an integrated structure, which takes up a lot of space during transportation and increases the time cost of transporting a large number of guardrails.

[0023] In view of this, the present invention provides a quick-installation protective device for municipal construction. Through the cooperation between the mounting parts, the connecting parts, and the spring, when the guardrail needs to be assembled, the connecting parts are inserted into the inner wall of the mounting parts. During the insertion process, the positioning rod is squeezed by the outer wall of the mounting parts, which compresses the spring and causes the connecting parts to slide at both ends of the inner wall of the cross frame until the positioning rod is inserted into the inner wall of the positioning groove, thus fixing the cross frame and the main frame together. When the guardrail needs to be disassembled, personnel only need to manually press the connecting parts to disengage the positioning rod from the inner wall of the positioning groove.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] Example 1: By Figure 1-6It is known that a quick-installation protective device for municipal construction includes a main frame 1, of which two main frames 1 are provided. A horizontal frame 11 is provided above and below the two main frames 1. Positioning devices 2 are provided at both ends of each horizontal frame 11. The positioning devices 2 include: two mounting parts 21, respectively fixed to the sides of the two main frames 1 that are close to each other; two positioning grooves 22, respectively formed on the upper and lower inner walls of the mounting parts 21; two connecting parts 23, respectively slidably engaged with the upper and lower sides of the horizontal frame 11; and springs 24, fixed to the two... Between each connector 23; two positioning rods 25 are provided, which are respectively fixed to the side of the two connectors 23 that are close to each other and inserted into the inside of the positioning groove 22; a connecting part 26 is provided on the outer wall of the two main frames 1; wherein, by inserting the connector 23 into the inner wall of the mounting part 21, the positioning rod 25 is squeezed by the mounting part 21, which compresses the spring 24 until the positioning rod 25 is inserted into the inner wall of the positioning groove 22, connecting the cross frame 11 and the main frame 1, and connecting multiple main frames 1 through the connecting part 26;

[0026] In the specific implementation process, it is worth noting that when the guardrail needs to be assembled, the connector 23 is inserted into the inner wall of the mounting part 21. During the insertion process, the positioning rod 25 will be squeezed by the outer wall of the mounting part 21, compressing the spring 24, so that the connector 23 slides on both ends of the inner wall of the cross frame 11 until the positioning rod 25 is inserted into the inner wall of the positioning groove 22, thus fixing the connection between the cross frame 11 and the main frame 1. When the guardrail needs to be disassembled, personnel only need to manually press the connector 23 to make the positioning rod 25 disengage from the inner wall of the positioning groove 22.

[0027] Furthermore, the connecting part 26 includes: a mounting ear 261, fixedly connected to one side of the outer wall of a main frame 1; a connecting ear 262, fixedly connected to one side of the outer wall of another main frame 1; and a fixing bolt 263, threadedly connected to the inner walls of the mounting ear 261 and the connecting ear 262; wherein, by inserting the connecting ear 262 of one main frame 1 into the inner wall of another main frame 1 with a mounting ear 261, and then fixing the position of the mounting ear 261 and the connecting ear 262 by the fixing bolt 263, multiple main frames 1 are connected;

[0028] In the specific implementation process, it is worth noting that when multiple main frames 1 need to be connected, simply insert the connecting ear 262 on the outer wall of one main frame 1 into the inner wall of the mounting ear 261 on the outer wall of another main frame 1, and then fix the positions of the mounting ear 261 and the connecting ear 262 with the fixing bolt 263, so that multiple main frames 1 can be assembled.

[0029] Specifically, when using this municipal construction quick-installation protective device, when the guardrail needs to be assembled, the connector 23 is inserted into the inner wall of the mounting part 21. During the insertion process, the positioning rod 25 is squeezed by the outer wall of the mounting part 21, compressing the spring 24, causing the connector 23 to slide at both ends of the inner wall of the cross frame 11 until the positioning rod 25 is inserted into the inner wall of the positioning groove 22, thus fixing the connection between the cross frame 11 and the main frame 1. When the guardrail needs to be disassembled, personnel only need to manually press the connector 23 to disengage the positioning rod 25 from the inner wall of the positioning groove 22. When multiple main frames 1 need to be connected, simply insert the connecting ear 262 on the outer wall of one main frame 1 into the inner wall of the mounting ear 261 on the outer wall of another main frame 1, and then fix the positions of the mounting ear 261 and the connecting ear 262 with the fixing bolt 263, thus assembling multiple main frames 1.

[0030] Example 2: From Figure 1-6 It can be seen that multiple protective rods 3 penetrate through the top of the cross frame 11 and are inserted into the bottom of the inner wall of the cross frame 11;

[0031] In the specific implementation process, it is worth noting that multiple protective rods 3 can be fixed by plugging them in. When disassembly is required, multiple protective rods 3 can also be disassembled to avoid occupying too much transportation space.

[0032] Furthermore, foot pads 4 are fixedly connected to the bottom of both main frames 1;

[0033] In the specific implementation process, it is worth noting that, through the function of foot pad 4, the guardrail can sit more stably on the ground;

[0034] Furthermore, a support frame 5 is bolted between the main frame 1 and the foot pads 4;

[0035] In the specific implementation process, it is worth noting that, through the function of the support frame 5, when the guardrail is hit, the support frame 5 can play a certain supporting role, preventing the guardrail from falling down directly upon impact.

[0036] Specifically, based on the above embodiment one, multiple guardrails 3 are fixed by plugging in. When disassembly is required, multiple guardrails 3 can also be disassembled to avoid occupying too much transportation space. With the help of the foot pads 4, the guardrail can sit more stably on the ground. With the help of the support frame 5, when the guardrail is hit, the support frame 5 can provide a certain support to prevent the guardrail from falling over directly.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
