[0022] like Figure 1 As shown, a precise positioning auxiliary device for installing PVC conduit in structural panels (hereinafter referred to as the auxiliary device) includes a horizontally arranged adjustment frame 3, and an adjustment groove 1 is provided in the middle of the adjustment frame 3. The adjustment groove 1 is a through groove vertically opened on the upper and lower end faces of the adjustment frame 3.

[0023] An adjusting sleeve 4 is fixed at the middle of the front and rear end faces along the length of the adjusting frame 3. The adjusting sleeve 4 is a threaded sleeve with internal threads. An adjustable support foot 5 is threadedly connected to the front and rear adjusting sleeves 4 respectively. An adjustable diagonal brace 2 is also provided on both sides of each adjustable support foot 5. The two adjustable diagonal braces 2 located on the same end face are located at the ends of the corresponding end faces.

[0024] Multiple fixing sleeves 6 for fixing PVC pipes are installed side by side in the adjusting groove 1. Each fixing sleeve 6 is slidably set in the adjusting groove 1, combined with... Figure 2 A scale 7 is also provided on the upper surface of the adjustment frame 3. During actual construction, the scale 7 is used to accurately position the fixed sleeve 6 according to the design drawings.

[0025] like Figure 3As shown, the fixing sleeve 6 includes a fixing cylinder 10, the top of which is closed. A locking screw 8 is coaxially fixed to the top of the fixing cylinder 10, and a locking cap 9 is threaded onto the outside of the locking screw 8. After removing the locking cap 9, the locking screw 8 is passed through the adjusting groove 1 from bottom to top, and the locking cap 9 is reinstalled on the surface of the locking screw 8 so that the fixing cylinder 10 can slide along the adjusting groove 1. After determining the construction position of the fixing cylinder 10, the locking cap 9 is tightened to fix the relative position of the fixing cylinder 10 and the adjusting frame 3.

[0026] The lower end of the fixed cylinder 10 is an open end. A fixing clamp 11 is provided at the lower part of the fixed cylinder 10. The fixing clamp 11 includes a screw and an adjusting handle coaxially fixed to the end of the screw. The fixing clamp 11 is radially inserted into the outside of the fixed cylinder 10 through the screw inside and is threadedly connected to the cylinder wall of the fixed cylinder 10. By rotating the adjusting handle, the depth of the screw in the fixing clamp 11 entering the fixed cylinder 10 can be adjusted so as to lock or release the PVC pipe inserted into the fixed cylinder 10.

[0027] like Figure 4 As shown, the adjustable support foot 5 includes an adjusting screw 13, which passes through an adjusting sleeve 4 on the side of the adjusting frame 3 and is threadedly connected to the adjusting sleeve 4.
