[0038] There are two pin pieces 4 and they are symmetrically arranged inside the pin rod 3. The longitudinal section of the pin piece 4 is an inverted triangle structure. The bottom ends of the pin pieces 4 are rotatably connected to the second fixed rod 302 inside the pin rod 3, and the two pin pieces 4 are located in the hollow structure inside the pin rod 3 and are respectively located at the openings on both sides of the pin rod 3.

[0039] A stopper 303 is provided in the hollow structure. The stopper 303 is located at the top of the hollow structure, and two of them are provided, symmetrically arranged at the openings on both sides to form an opening. A baffle 401 is provided on one side of each pin piece 4 close to another pin piece 4. The height of the baffle 401 is greater than the height of the opening and less than the height of the hollow structure.

[0040] The elastic component includes a spring sheet 5 located in the hollow structure. The lower part of the spring sheet 5 is sleeved on the first fixing rod 301 . The first fixing rod 301 is fixedly connected in the hollow structure and arranged parallel to the second fixing rod 302 and located between the two second fixing rods 302 .

[0041] The upper portion of the spring sheet 5 includes two spring sheet bodies, and the top ends of the two spring sheet bodies abut against the inner sides of the two pin sheets 4 respectively.

[0042] When the utility model is installed, the pin sheet 4 and the spring sheet 5 are first installed on the first fixing rod 301 and the second fixing rod 302 inside the pin rod 3 respectively, and then the two halves of the pin rod 3 are buckled together, and finally the sleeve 201 and the pin rod 3 are welded together to complete the assembly.

[0043] When the utility model is used, when welding the steel mesh body 1, a certain number of pins 2 are inserted, and when closing the hole, the pins 2 are aligned with the pin holes of the aluminum mold and buckled, and the pins 2 can be self-locked. When opening the hole, the pin piece 4 is pressed from the bottom of the aluminum mold into the pin rod 3, and can be pulled out.

[0044] Embodiment 2

[0045] like Figures 1 to 4As shown, this embodiment is a self-locking protective mesh suitable for fixing aluminum molds. The difference from the embodiment is that the sleeve 201 includes a U-shaped frame 6, the U-shaped frame 6 includes two parallel fixed plates 601, one end of the two fixed plates 601 is fixedly connected by a connecting plate 602, and the connecting plate 602 is perpendicular to the fixed plate 601, the open end of the U-shaped frame 6 is movably connected by a locking piece, and the two fixed plates 601 of the U-shaped frame 6 are provided with symmetrical through holes 603 at one end near the opening, and the locking piece is movably connected in the through hole 603.

[0046] The locking piece includes an insert rod 7, which includes a columnar rod body and a pull ring 701 at the top. The rod body of the insert rod 7 is located in a through hole 603 of a fixed plate 601 away from the pin rod 3, and is slidably connected in accordance with the diameter of the through hole 603. The pull ring 701 is located above and outside the through hole 603. A connecting disk 702 is fixedly provided near the bottom end of the rod body of the insert rod 7.

[0048] When the present embodiment is used, the insertion rod 7 on the upper part of the pin 2 can be quickly fixed on the existing steel mesh body 1. In the initial state of the spring 703, the bottom end of the insertion rod 7 is located in the through hole 603 of the fixing plate 601 at the bottom of the U-shaped frame 6, thereby realizing the closed state of the sleeve 201, so that it can be locked on the steel bar of the mesh body 1.
