[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a construction site protection fence, which includes two side frames 1, and a fence frame 2 is clamped between the opposite surfaces of the two side frames 1;

[0031] Orifice plates 21 are welded at the upper and lower positions on both sides of the fence frame 2, and movable channels 13 are opened at the upper and lower positions on both sides of the side frame 1. Support blocks 11 are welded on both sides of the side frame 1 and below each movable channel 13. A positioning rod 12 that is clamped with the inner hole of the orifice plate 21 is welded at the center of the top of the support block 11. A clamping assembly 3 is installed inside the side frame 1, and the movable end of the clamping assembly 3 is clamped with the positioning rod 12.

[0032] The clamping assembly 3 includes a vertical rod 31 that slides inside the side frame 1, and the top of the vertical rod 31 is located above the side frame 1. A pull ring plate 39 is welded to the top of the vertical rod 31, and the pull ring plate 39 is more conducive to applying an upward pulling force to the vertical rod 31. Both sides of the vertical rod 31 are covered with lifting slides 33, and the two sides of the lifting slides 33 are respectively located inside the active channels 13 on both sides. Both sides of the lifting slides 33 are welded with orifice plates 34 that are clamped with the positioning rod 12.

[0033] After the orifice plate 1 21 is placed on the top of the receiving block 11 and is engaged with the positioning rod 12 , the orifice plate 2 34 is engaged with the positioning rod 12 and pressed on the top of the orifice plate 1 21 .

[0034] A hole plate 37 is welded to the upper side of the inside of the side frame 1, and a sliding hole for the vertical rod 31 to pass through is opened in the middle of the hole plate 37. A retaining ring 35 is welded to the outer wall of the vertical rod 31 and is located below the hole plate 37. A spring 36 is sleeved on the outer wall of the vertical rod 31 and is located between the retaining ring 35 and the hole plate 37. The spring 36 can automatically reset the vertical rod 31 after being pulled.

[0035] A square block 32 is welded to the bottom end of the vertical rod 31, and the square block 32 slides vertically inside the side frame 1, so that the vertical rod 31 can only move vertically and straightly.

[0036] By means of the snap-fit ​​installation between the side frames 1 and the fence frames 2, the fence frames 2 are snap-fitted between the side frames 1 on both sides, which simplifies the locking installation method and facilitates the rapid disassembly of the fence frames 2, so as to facilitate the corresponding replacement of a damaged fence frame 2 at a later time. At the same time, two fence frames 2 can be installed between three fence frames 2, three fence frames 2 can be installed between four fence frames 2, and so on. Multiple fence frames 2 can be connected into one piece to improve the stability of the fence installation.

[0037] During use, the vertical rods 31 on both sides are pulled upward at the same time to move the retaining ring 35 upward and compress the spring 36. At this time, the orifice plate 2 34 is disengaged from the clamping connection with the positioning rod 12. Then, the fence frame 2 is placed between the side frames 1 on both sides, and the orifice plates 21 on both sides are clamped with the corresponding positioning rods 12. Under the lifting action of the receiving block 11 on the orifice plate 21, the fence frame 2 is clamped between the side frames 1 on both sides. Then, the upward pulling force applied to the vertical rod 31 is released. Under the resetting action of the spring 36, the vertical rod 31 is moved upward, so that the orifice plate 2 34 is clamped back between the positioning rod 12, and the orifice plate 21 is pressed between the receiving block 11 and the vertical rod 31. Similarly, the fence frame 2 can be disassembled.

[0038] Example 2

[0039] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0040] A slot 38 is provided on one side of the outer wall of the pull ring plate 39 and above the uppermost lifting slide bar 33 . A limit assembly 4 is fixedly installed on the top of the side frame 1 , and the clamping end of the limit assembly 4 enters into the slot 38 and is connected to the slot 38 .

[0041] The limiting assembly 4 includes two groups of rod seats 41 welded to the top of the side frame 1, a sliding rod 42 is welded between the opposite ends of the two rod seats 41 in the same group, a translation bar 43 is slidably installed between the two sliding rods 42, and sliding holes are opened at both ends of the translation bar 43 for sliding with the sliding rod 42, and a block 44 engaged with the slot 38 is welded on the side of the translation bar 43 close to the vertical rod 31. When the vertical rod 31 is pulled upward, the slot 38 is exposed at the top of the side frame 1, and the translation bar 43 is pushed in the direction of the vertical rod 31, so that the block 44 enters the internal slot 38 and engages. At this time, even if the upward pulling force applied to the vertical rod 31 is released, the vertical rod 31 will not move downward due to the elastic reset of the spring 36, and the vertical rod 31 will be temporarily limited, which is conducive to one person to operate the installation and disassembly of the fence, reduce the participation of manpower, and reduce the cost of workers by single-person operation.

[0042] An iron block is installed inside the slot 38, and a magnet 45 is embedded and installed on the side of the block 44 away from the translation bar 43, and the magnet 45 is magnetically attracted to the iron block. When the magnet 45 enters the slot 38, the magnet 45 will be magnetically attracted to the iron block inside the slot 38, thereby improving the firmness of the connection between the block 44 and the slot 38 and preventing it from detaching easily.

[0043] During use, when the vertical rod 31 is pulled upward, the slot 38 is exposed at the top of the side frame 1, and the translation bar 43 is pushed in the direction of the vertical rod 31, so that the block 44 enters the internal slot 38 for engagement. At this time, even if the upward pulling force applied to the vertical rod 31 is released, the vertical rod 31 will not move downward due to the elastic return of the spring 36, and the vertical rod 31 will be temporarily limited, which is convenient for one person to operate the installation and disassembly of the fence.

[0044] The remaining structures are the same as those of Example 1.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
