[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, a protective fence with a quick installation device includes a protective fence body 2, and quick-release bases 1 and connecting plugs 3 are respectively provided on both sides of the protective fence body 2 for facilitating the installation and connection of each protective fence body 2. The quick-release base 1 includes a fixing seat 113, and a circular through hole 106 is provided on the top of the fixing seat 113. The hole wall of the circular through hole 106 is slidably sleeved on the side of the positioning pin rod 104. The top of the positioning pin rod 104 is fixedly connected to the bottom end of the connecting rod 110. The top of the connecting rod 110 is fixedly connected to the outside of the pull ring 109. The side of the connecting rod 110 is slidably inserted into the hole wall of the circular through hole 2 111. The circular through hole 2 111 is opened at the top of the U-shaped reaction plate 112, and the two ends of the bottom of the U-shaped reaction plate 112 are fixedly connected to the top of the fixing seat 113.

[0024] The above design realizes the connection of each protective fence body 2 by connecting the connecting plug 3 on one protective fence body 2 with the quick-release base 1 on another protective fence body 2; since the connection and disassembly of the quick-release base 1 and the connecting plug 3 are very quick, the disassembly and assembly of each protective fence body 2 is also very quick. At the same time, the quick-release base 1 and the connecting plug 3 are an integral structure with the protective fence body 2, and no parts will fall off or be lost.

[0025] Specifically, the side wall of the connecting rod 110 is inserted into the inner circle of the spring 103, and the two ends of the spring 103 are supported between the positioning pin rod 104 and the U-shaped reaction plate 112. The side of the connecting rod 110 is fixedly connected to one side of the limit block 101, and the hole wall of the circular through hole 111 is provided with a through groove 102 for the limit block 101 to pass through. The bottom end of the positioning pin rod 104 is spherical 105. One side of the fixed seat 113 is fixedly connected to one side of the protective fence body 2, and the other side of the fixed seat 113 is provided with a cavity 108, and the cavity 108 is provided with a spring 114, one end of the spring 114 is fixedly connected to one side of the slider 107, and the other end of the spring 114 is fixedly connected to the side wall of the cavity 108.

[0026] With the above design, when each group of protective fence bodies 2 needs to be disassembled, it is only necessary to pull the pull ring 109 upwards, and the pull ring 109 drives the positioning pin rod 104 to move upwards through the connecting rod 110, so that the positioning pin rod 104 is pulled out of the positioning hole 304. At the same time, the limit block 101 will also move upwards and pass through the through groove 102 to the top of the U-shaped reaction plate 112. At this time, the pull ring 109 is twisted, and the pull ring 109 drives the connecting rod 110 and the limit block 101 to rotate, so that The limit block 101 is staggered with the through slot 102, so when the pull ring 109 is loosened, the U-shaped reaction plate 112 will prevent the limit block 101 from moving downward, thereby preventing the positioning pin rod 104 from moving downward and inserting into the positioning hole 304, so that the connecting block 306 can be pulled out of the cavity 108. At the same time, the spring 114 will rebound and push the slider 107, and the slider 107 will push the connecting block 306 out of the cavity 108, thereby playing a certain resistance role and facilitating disassembly.

[0027] Specifically, the connection plug 3 includes a U-shaped connection plate 301, one side of the U-shaped connection plate 301 is fixedly connected to one side of the protective fence body 2, the top and bottom of the U-shaped connection plate 301 can be provided with a circular through hole 302, the hole wall of the circular through hole 302 is rotatably sleeved on the side of the rotating shaft 303, the side of the rotating shaft 303 is fixedly inserted into the inside of the connection block 306, one end of the connection block 306 is slidably inserted into the cavity 108, a positioning hole 304 is provided on the top of the connection block 306, and the hole wall of the positioning hole 304 is slidably sleeved on the bottom end of the positioning pin rod 104. One end of the connection block 306 is set as a slope structure 305.

[0028] The above design, when installing, only needs to insert the connection block 306 on one of the protective fence bodies 2 into the fixing seat 113 on the other protective fence body 2 to complete the connection, which is very convenient and quick. Specifically, when the connection block 306 is inserted into the cavity 108 of the fixing seat 113, the inclined surface 305 at the end of the connection block 306 will push the spherical surface 105 at the bottom of the positioning pin rod 104, so that the positioning pin rod 104 moves upward, and the positioning pin rod 104 compresses the spring 103 at the same time. The coordinated use of the inclined surface 305 and the spherical surface 105 makes the friction resistance between the connection block 306 and the positioning pin rod 104 smaller. At the same time, when the connecting block 306 is inserted into the cavity 108, the connecting block 306 pushes the slider 107, and the slider 107 will compress the spring 2 114. When the connecting block 306 is inserted into the positioning hole 304 on the upper part and is aligned with the bottom end of the positioning pin rod 104, the spring 103 pushes the positioning pin rod 104 to move down and insert into the positioning hole 304. The positioning pin rod 104 is inserted into the circular through hole 106 and the positioning hole 304 at the same time, so that the connecting block 306 and the fixing seat 113 cannot be separated, thereby realizing the connection between the two groups of protective fence bodies 2. According to the above method, each protective fence body 2 can be connected in turn, and the connecting block 306 and the U-shaped connecting plate 301 can be rotated, which allows the two groups of protective fence bodies 2 to rotate, so that multiple groups of protective fence bodies 2 can be placed in a non-linear manner according to specific construction requirements, thereby improving the applicability of the protective fence body 2.

[0029] Working principle: During installation, when the connecting block 306 is inserted into the cavity 108 of the fixing seat 113, the inclined surface 305 at the end of the connecting block 306 will push the spherical surface 105 at the bottom end of the positioning pin 104, causing the positioning pin 104 to move upward, while compressing the spring 103. When the connecting block 306 is inserted into the positioning hole 304 on its upper part and aligned with the bottom end of the positioning pin 104, the spring 103 pushes the positioning pin 104 to move downward and insert into the positioning hole 304. The positioning pin 104 is inserted into the circular through hole 106 and the positioning hole 304 at the same time, so that the connecting block 306 cannot be separated from the fixing seat 113, thereby realizing the connection between the two sets of protective fence bodies 2. According to the above method, each protective fence body 2 can be connected in sequence.

[0030] When the groups of protective fence bodies 2 need to be disassembled, it is only necessary to pull the pull ring 109 upwards. The pull ring 109 drives the positioning pin rod 104 to move upwards through the connecting rod 110, so that the positioning pin rod 104 is pulled out of the positioning hole 304. At the same time, the limit block 101 will also move up and pass through the through groove 102 to the top of the U-shaped reaction plate 112. At this time, the pull ring 109 is twisted, and the pull ring 109 drives the connecting rod 110 and the limit block 101 to rotate, so that the limit block 101 is staggered with the through groove 102. In this way, when the pull ring 109 is loosened, the U-shaped reaction plate 112 will hinder the limit block 101 from moving downward, thereby making it impossible for the positioning pin rod 104 to move downward and insert into the positioning hole 304, so that the connecting block 306 can be pulled out of the cavity 108. At the same time, the spring 2 114 will rebound and push the slider 107, and the slider 107 pushes the connecting block 306 out of the cavity 108, playing a certain resistance role, which is convenient for disassembly.
