[0035] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "top" and "bottom" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present invention. In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Refer to the appended Figure 1-8 drawings. In this embodiment, a safety protection device for municipal road construction is provided. Only a set of basic sections of this safety protection device is shown. During actual construction, multiple sets of basic sections can be freely combined according to the extension direction and length of the road. This basic section includes a support mechanism 100, a protection mechanism 200, a first distance adjustment mechanism 300, and a second distance adjustment mechanism 400. Two sets of the support mechanism 100 are arranged at intervals, and two sets of the protection mechanism 200 are arranged with a height difference. The two sets of the protection mechanism 200 are disposed between the two sets of the support mechanism 100; the first distance adjustment mechanism 300 is arranged on the support mechanism 100. One of its functions is to connect the support mechanism 100 and the protection mechanism 200 to provide conditions for the stable support of the protection mechanism 200, and the other function is to adjust the height difference between the two sets of the protection mechanism 200 to meet different protection construction requirements; the second distance adjustment mechanism 400 is located between the two sets of the protection mechanism 200. One of its functions is to cooperate with the first distance adjustment mechanism 300 to adjust the height difference between the two sets of the protection mechanism 200.

[0038] In this embodiment, a set of the first distance adjusting mechanism 300 is provided at each of the two long ends of the protection mechanism 200 to synchronously adjust the heights of the two long ends of the protection mechanism 200 and ensure the levelness of the protection mechanism 200. A vertical first sliding groove 111 is configured in the support mechanism 100. The first distance adjusting mechanism 300 includes a distance adjusting screw rod 310 rotatably connected to the first sliding groove 111, a sliding seat 320 threadedly connected to the distance adjusting screw rod 310, and a fixed seat 330 fixed to the outer wall of the support mechanism 100. The sliding seat 320 slidably abuts against the inner wall of the first sliding groove 111. One end of the distance adjusting screw rod 310 is configured with a rotating disc 340, and the rotating disc 340 is located outside the support mechanism 100, so that workers can change the height difference between the sliding seat 320 and the fixed seat 330 by screwing the rotating disc 340. The two sets of protection mechanisms 200 are respectively connected to the sliding seat 320 and the fixed seat 330. When the rotating disc 340 rotates, the distance adjusting screw rod 310 rotates accordingly. Due to the abutting and limiting effect of the inner wall of the first sliding groove 111, the sliding seat 320 cannot rotate but can only move along the axial direction of the distance adjusting screw rod 310, so that the height difference between the sliding seat 320 and the fixed seat 330 changes, and further the height difference between the two sets of protection mechanisms 200 respectively connected to the sliding seat 320 and the fixed seat 330 changes.

[0039] For the convenience of installation and disassembly, a second sliding groove 321 is configured in the sliding seat 320. A guide rod 350 extending along the width direction of the protection mechanism 200 is configured in the second sliding groove 321. There are two sets of guide rods 350 arranged in parallel. A return spring 360 and a limiting plate 370 are respectively sleeved on the two sets of guide rods 350. Two ends of the return spring 360 respectively abut against the inner wall of the second sliding groove 321 and the limiting plate 370. The other end of the limiting plate 370 is configured with a sliding buckle 380. The sliding buckle 380 is located between the two sets of guide rods 350 and can slide along the axial direction of the guide rod 350 with the limiting plate 370. A clamping groove 210 is configured on the protection mechanism 200 for connecting the sliding buckle 380.

[0040] A guiding inclined surface 381 is arranged on the sliding buckle 380. The guiding inclined surface 381 slopes gradually along the installation direction of the protection mechanism 200 from the limiting plate 370 to the clamping groove 210. When the protection mechanism 200 moves along its own installation direction and presses the guiding inclined surface 381 on the sliding buckle 380, the sliding buckle 380 is stressed and moves into the second sliding groove 321, and the limiting plate 370 presses the return spring 360. When the position of the clamping groove 210 corresponds to that of the sliding buckle 380 as the protection mechanism 200 moves, since the clamping groove 210 is recessed in the surface of the protection mechanism 200, the sliding buckle 380 loses the extrusion force. Therefore, the sliding buckle 380 resets under the elastic force of the return spring 360 and extends into the clamping groove 210, and is firmly clamped with the clamping groove 210. When it is necessary to disassemble the protection mechanism 200, hold the limiting plate 370 by hand and make it slide towards the return spring 360, which can drive the sliding buckle 380 to slide into the second sliding groove 321, and then separate the sliding buckle 380 from the clamping groove 210. At this time, the protection mechanism 200 can be removed from the sliding seat 320.

[0041] In this embodiment, the fixed seat 330 is located below the sliding seat 320. The two groups of protection mechanisms 200 are respectively located on the same side of the sliding seat 320 and the fixed seat 330, that is, the protection mechanism 200 at the higher position is located above the sliding seat 320, and the protection mechanism 200 at the lower position is located above the fixed seat 330. A connecting bolt 390 for connecting the protection mechanism 200 at the lower position is arranged on the fixed seat 330. Through the supporting effects of the sliding seat 320 and the fixed seat 330 on the two groups of protection mechanisms 200, the structural stability of this safety protection device is improved.

[0042] In addition, to improve the connection stability, in this embodiment, at least the protection mechanism 200 at the higher position has a U-shaped groove 220 with an opening facing downwards, and the U-shaped groove 220 is buckled on the sliding seat 320.

[0043] In this embodiment, the second distance adjusting mechanism 400 is disposed on the high side of the protection mechanism 200, and its top and bottom ends are respectively connected to different protection mechanisms 200, cooperating with the first distance adjusting mechanism 300 to adjust the height difference between the two groups of protection mechanisms 200, and providing support to the middle part of the protection mechanism 200, improving the stability and protection effect of this safety protection device; the second distance adjusting mechanism 400 includes a first rod 410 and a second rod 420 which are slidably connected, and the separated ends of the first rod 410 and the second rod 420 are respectively rotatably connected to different protection mechanisms 200. When the first rod 410 and the second rod 420 slide, the overlapping degree of the two changes, and the distance between the separated ends of the two changes, thereby changing the height difference between the two groups of protection mechanisms 200 located at the top and bottom ends of the second distance adjusting mechanism 400 respectively. When the two groups of protection mechanisms 200 are detached from the first distance adjusting mechanism 300, the two groups of protection mechanisms 200 can also be stacked together by rotating the first rod 410 and the second rod 420, saving storage and transportation space. It should be noted that before rotating the first rod 410 and the second rod 420 to stack the two groups of protection mechanisms 200, it is best to first slide the first rod 410 and the second rod 420 to make their overlapping degree reach the highest, so as to further save storage and transportation space.

[0044] Of course, U-shaped grooves 220 can also be provided on both groups of protection mechanisms 200. The U-shaped grooves 220 on the two groups of protection mechanisms 200 face each other, and the groove width of the U-shaped groove 220 is adapted to the cross-sectional dimensions of the first rod 410 and the second rod 420, so that the first rod 410 and the second rod 420 can be hidden in the U-shaped groove 220 after rotation, enabling the two groups of protection mechanisms 200 to be stacked with almost no distance (referring to the distance in the height direction), so as to further save storage and transportation space.

[0045] In this embodiment, the first rod 410 is a hollow rod, and its side wall is configured with a third chute 411 communicating the inside and outside of the first rod 410; one end of the second rod 420 slidably penetrates through the first rod 410, and its side wall is configured with a guiding slider 430 slidably connected to the third chute 411. The surrounding effect of the first rod 410 on the second rod 420 can improve the connection stability of the two and ensure the smoothness of their relative sliding. The cooperation between the guiding slider 430 and the third chute 411 can further improve the direction stability and sliding smoothness of the second slide rod, improving the structural stability and use convenience of this safety protection device.

[0046] Reference appendix Figure 1, the support mechanism 100 includes a support column 110 and a support base 120. The first chute 111 is located on the support column 110, so the first distance adjustment mechanism 300 is arranged on the support column 110; the support base 120 is disposed at the bottom of the support column 110, and its cross-sectional area is larger than that of the support column 110, which improves the support stability by increasing the contact area with the ground.

[0047] When installing this safety protection device: first, support the two groups of support mechanisms 100 stably at a preset distance, then rotate the rotating disk 340 to adjust the height difference between the sliding seat 320 and the fixed seat 330, and then connect the two groups of protection mechanisms 200 to the sliding seat 320 and the fixed seat 330 respectively.

[0048] Compared with the prior art, the present invention has at least the following beneficial effects: the first distance adjustment mechanism 300 enables quick installation, disassembly, and height difference adjustment of the protection mechanism 200, so that this safety protection device can adapt to different protection construction requirements. The second distance adjustment mechanism 400 assists in adjusting the height difference of the protection mechanism 200, and enables the protection mechanism 200 to be stacked after the protection mechanism 200 is disassembled, reducing the storage and transportation space required for this safety protection device and avoiding the problem of easy structural damage caused by transporting it in the unfolded state.

[0049] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
