DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-5 This application is described in further detail. Example

[0025] Combination Figure 1-Figure 5The embodiment of the present application discloses a fixing structure of a pre-embedded part for connecting a pipe segment, including a D-piece body 2 on a pipe segment mold end plate 1, the number of the pipe segment mold end plates 1 is two, a magnetic box body 3 is fixedly installed in the middle of the top of the opposite side of the two pipe segment mold end plates 1 by bolt penetration, two symmetrical positioning components 4 are arranged between the pipe segment mold end plate 1 and the D-piece body 2, a notch 5 is opened on the D-piece body 2, four locking components 6 are arranged between the D-piece body 2 and the pipe segment mold end plate 1, the locking component 6 includes a fixed tube 61 fixedly connected to the pipe segment mold end plate 1, the inner cavity of the fixed tube 61 is slidably connected to a movable rod 62, one end of the movable rod 62 penetrates through one side of the pipe segment mold end plate 1, and the movable rod 62 is fixedly connected to the inner cavity of the fixed tube 61. The end of the movable rod 62 close to the D-piece body 2 passes through the slot 5 and is fixedly connected to a locking block 63, which abuts against the inner side of the D-piece body 2. The end of the movable rod 62 away from the D-piece body 2 is fixedly connected to an ear block 64. The surface of the ear block 64 is rotatably connected to an arc-shaped pressing sleeve 65 through a rotating shaft. A lower pressing rod 66 is welded to one side of the arc-shaped pressing sleeve 65. The surface of the movable rod 62 is slidably connected to a movable plate 67. A spring 68 is provided on the surface of the movable rod 62 close to the fixed tube 61. Both ends of the spring 68 are in contact with the fixed tube 61 and the movable plate 67 respectively. The four locking components 6 are respectively located at 1 / 6, 1 / 3, 2 / 3 and 5 / 6 in the width direction of the end plate 1 of the tube segment mold. Example

[0026] Combination Figure 1-Figure 5 The positioning assembly 4 includes a threaded hole 41 formed on the end plate 1 of the segment mold. A movable hole 43 is formed on one side of the inner cavity of the threaded hole 41. A bolt 42 is threadedly connected to the inner cavity of the threaded hole 41. One end of the bolt 42 extends to the inner cavity of the movable hole 43 and is fixedly connected to a rubber sleeve 44. The rubber sleeve 44 passes through the slot 5 and extends to the inner cavity of the D-piece body 2. The diameter of the rubber sleeve 44 is the same as the width of the inner cavity of the slot 5. The end of the rubber sleeve 44 is arc-shaped and the rubber sleeve 44 can be deformed. The arc-shaped end of the rubber sleeve 44 facilitates the rubber sleeve 44 to pass through the slot 5 and enter the inner cavity of the D-piece body 2. The deformability of the rubber sleeve 44 reduces the friction between the rubber sleeve 44 and the D-piece body 2, making positioning easier. The width of the locking block 63 is smaller than the width of the inner cavity of the slot 5. The setting of the width of the locking block 63 being smaller than the width of the inner cavity of the slot 5 facilitates the locking block 63 to pass through the slot 5 and enter the inner cavity of the D-piece body 2, thereby reducing the resistance during installation of the D-piece body 2 and improving the convenience of installation of the D-piece body 2.

[0027] Working principle: When the utility model is used, the user adsorbs the D-piece body 2 to the inner side of the end plate 1 of the segment mold through the magnetic force of the magnetic box body 3 installed on the end plate 1 of the segment mold, and then picks up the socket wrench, puts it on the surface of the bolt 42 and rotates it, so that the bolt 42 cooperates with the threaded hole 41, so that the bolt 42 and the rubber sleeve 44 move to the inner side of the end plate 1 of the segment mold and rotate. During this period, the arc end of the rubber sleeve 44 cooperates with the deformable body, passes through the magnetic box body 3 and enters the inner cavity of the D-piece body 2 to realize the positioning of the D-piece body 2. During the process of the D-piece body 2 being adsorbed on the inner side of the end plate 1 of the segment mold, the horizontal locking block 63 will pass through the notch 5 to enter Into the inner cavity of the D-piece body 2, the user then holds the pressing rod 66 to rotate the arc-shaped pressing sleeve 65, the ear block 64, the movable rod 62 and the locking block 63 by ninety degrees, so that the locking block 63 is facing downward, and then presses down the pressing rod 66 to rotate the arc-shaped pressing sleeve 65 by ninety degrees. The arc-shaped pressing sleeve 65 rotates on the surface of the ear block 64, so that the arc-shaped protrusion of the arc-shaped pressing sleeve 65 presses against the movable plate 67, so that the movable plate 67 moves toward the fixed tube 61 and squeezes the spring 68. The restoring force of the spring 68 eventually moves the movable rod 62 outward, so that the locking block 63 firmly presses against the inner side of the D-piece body 2, and the D-piece body 2 is fixed in the pipe segment mold.

[0028] In summary: the segment connection embedded parts fixing structure realizes the pre-fixation of the D-part body 2 by magnetically attracting the D-part body 2 through the magnetic box body 3, and then operates the positioning component 4 to make the rubber sleeve 44 enter the inner cavity of the slot 5 to realize the positioning of the D-part body 2. The locking block 63 at the end of the movable rod 62 passes through the slot 5 in a horizontal state and enters the inner cavity of the D-part body 2. 92 and 93 are rotated ninety degrees, and then the pressing rod 66 is pressed down, so that the arc-shaped pressing sleeve 65 drives the movable rod 62 to move outward, and then drives the locking block 63 to press against the inner side of the D-part body 2, so that the D-part body 2 can be fixed in the segment mold, so as to achieve the pre-fixation of the D-part by using the magnetic box, and then the positioning component is used to position the D-part to prevent displacement. Finally, the locking component is used to firmly fix the D-part in the segment mold, thereby ensuring the accuracy of the position of the D-part and the purpose of rapid installation.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
