[0035] The following is combined Figures 1-4 The technical solution provided by this utility model will be described in more detail.
[0036] Example 1:
[0037] See Figures 1-5As shown, the elastic locking assembly provided by this utility model includes a screw body 1, an elastic element 2, a handle part 3, and a locking nut 4. The screw body 1 has an end head 5 fixed at its end. The end head 5 can pass through the waist-shaped hole 71 on the ice dam 100 and extend into the ice dam 100. The end head 5 can be positioned inside the ice dam 100 after the screw body 1 rotates at a preset angle. The elastic element 2 is sleeved on the outside of the screw body 1. The handle part 3 is detachably connected to the screw body 1. The locking nut 4 is located on the outside of the handle part 3 and is threadedly connected to the screw body 1 to lock the elastic element 2, thereby pressing the elastic element 2 between the bottom of the boundary wall 200 and the handle part 3.
[0038] In this embodiment, the elastic locking assembly features a handle 3 for easy rotation or pressing of the screw body 1, and an end 5 that can be positioned inside the ice dam 100 after the screw body 1 has rotated to a preset angle, facilitating installation. After the screw body 1 and ice dam 100 are assembled, the bottom wall of the boundary wall 200 passes through the screw body 1 and is tightly attached to the ice dam 100. Then, the elastic element 2, handle 3, and locking nut 4 are sequentially assembled onto the screw body 1, and the locking nut 4 is tightened. The elastic element 2 is pressed between the bottom wall of the boundary wall 200 and the handle 3, locking the boundary wall 200 and ice dam 100 together. When an athlete collides head-on with the boundary wall 200, the bottom wall of the boundary wall 200 tilts up, creating a gap between it and the ice dam 100. The elastic element 2 is compressed by the side wall of the boundary wall 200, providing a certain degree of cushioning.
[0039] As an optional implementation, see Figure 2 and Figure 3 As shown, a guide groove 11 is provided on the screw body 1. The guide groove 11 is arranged along the axis of the screw body 1. One end of the guide groove 11 is a closed end, and the handle part 3 is slidably connected to the guide groove 11. The other end of the guide groove 11 is an open end, which extends to one end of the screw body 1 away from the head 5. The side opening of the guide groove 11 is connected to the outer side wall of the screw body 1.
[0040] After removing lock nut 4, see Figure 3 As shown, the handle 3 can slide out along the guide groove 11, thereby separating from the screw body 1, which facilitates the installation and removal of the partition wall 200.
[0041] As an optional implementation, see Figure 3 As shown, the handle 3 includes a guide plate 31 and a knob 32, wherein the knob 32 is fixedly connected to the guide plate 31, the guide plate 31 is provided with a central hole, a slider is provided on the wall of the central hole, the screw body 1 passes through the central hole, and the slider extends into the guide groove 11 and is slidably connected with the guide groove 11.
[0042] The guide plate 31 is connected to the guide groove 11 sliding rod, and the handle 32 is easy to hold. The user can hold the handle 32 to rotate the screw body 1 or press down the screw body 1.
[0043] As an optional implementation, see Figure 3 As shown, the handle 32 includes a plate 321 and a connecting shaft 322, wherein: the two plates 321 are fixedly connected to the opposite sides of the guide plate 31 respectively, and the connecting shaft 322 fixes the two plates 321 together.
[0044] The aforementioned handle 32 facilitates the fixed connection between the handle 32 and the guide plate 31, making it convenient for the user to hold.
[0045] As an optional implementation, see Figure 2 and Figure 3 As shown, the diameter of the elastic element 2 gradually increases along the direction closer to the end 5.
[0046] As the locking nut 4 is continuously tightened, the elastic element 2 is continuously pressed, and the elastic force of the elastic element 2 gradually increases, which helps to improve the stability of the structure.
[0047] As an optional implementation, see Figure 2 As shown, the elastic locking assembly also includes a plate 6, which is sleeved on the screw body 1 and used to abut against the bottom wall of the boundary wall 200 and the bottom end of the elastic element 2.
[0048] The flat plate 6 is attached to the bottom wall surface of the boundary wall 200, and the elastic element 2 can easily abut against it, which improves the stability of the structure.
[0049] The elastic locking assembly of this embodiment, during installation, such as Figure 1 , Figure 4 and Figure 5 As shown, the precast component 7 is fixed to the ice dam 100, and the waist-shaped hole 71 is opened on the precast component 7 so that the end 5 corresponds to the waist-shaped hole 71. The end 5 is a waist-shaped block, as shown in the figure. Figure 4 Insert end 5 into the ice dam 100, then hold handle 3 and rotate screw body 1 90°. This positions end 5 within the ice dam 100, preventing it from coming out. Remove handle 3, and pass the bottom wall of boundary wall 200 through screw body 1, ensuring the bottom wall of boundary wall 200 fits against the ice dam 100. Figure 1 , Figure 2 Then install the plate 6, elastic element 2, handle 3, and locking nut 4. Tighten the locking nut 4, which presses the elastic element 2 between the bottom of the boundary wall 200 and the handle 3. When an athlete crashes head-on into the boundary wall 200, the bottom wall of the boundary wall 200 tilts up, creating a gap between it and the ice dam 100. The elastic element 2 is compressed by the side wall of the bottom wall of the boundary wall 200, providing a certain cushioning effect.
