[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a fastening fixture for processing tee pipes, including a device body 1. A shaft 2 is fixedly connected to the upper part of the device body 1. A linear array of connecting parts 3 is rotatably sleeved on the outer side of the shaft 2. A rotating plate 4 is rotatably connected to the upper part of the connecting parts 3. Two symmetrically arranged clamping plates 5 are rotatably connected to the upper part of the rotating plate 4. An installation port is opened on one side of the clamping plate 5. An adjusting block 6 is rotatably connected in the installation port. A bidirectional screw 7 is arranged between the two clamping plates 5. Two mirror-symmetrical external threads are arranged on the outer side of the bidirectional screw 7. The two adjusting blocks 6 are threaded on the outer side of the bidirectional screw 7, and the two adjusting blocks 6 are respectively threaded on the two external threads in the bidirectional screw 7.
[0022] Insert the end of the tee pipe into the two clamping plates 5 of the same group, and then rotate the double-acting screw 7. The double-acting screw 7 will drive the movable ends of the two clamping plates 5 to move closer or further apart, and make the two clamping plates 5 cooperate to clamp the tee pipe to achieve a fastening effect.
[0023] like Figure 1 and Figure 4 As shown, the connector 3 includes a rotating rod 301, a track groove 302 is provided on the upper part of the rotating rod 301, a track block 303 is slidably arranged in the cavity of the track groove 302, the track block 303 is rotatably connected to the bottom of the rotating plate 4, and a shaft hole is provided at one end of the rotating rod 301, and the shaft 2 is located in the cavity of the shaft hole.
[0024] The vertical cross section of the track groove 302 is a convex cavity, and the vertical cross section of the track block 303 is a convex structure. By sliding the track block 303 in the track groove 302, the distance between the clamping plate 5 and the shaft 2 can be adjusted, and thus the clamping position of the clamping plate 5 can be easily adjusted according to the length of the T-tube.
[0025] like Figure 1 and Figure 3 As shown, a worm gear 8 is rotatably sleeved on the outer side of the shaft 2. The worm gear 8 is fixedly connected to the bottom of the bottom rotating rod 301, and a worm 9 is meshed on one side of the worm gear 8. The worm 9 is rotatably connected to the inner wall of the groove opened on the upper part of the device body 1.
[0026] By rotating the worm 9, the worm 9 drives the corresponding rotating rod 301 to rotate via the worm wheel 8, thereby causing the tee pipe to rotate and thus facilitating the adjustment of the tee pipe's installation angle.
[0027] like Figure 1 , Figure 3 and Figure 4 As shown, V-shaped grooves 10 are provided on the opposite side of the two clamping plates 5, and a stop block 11 is fixedly connected thereto. The stop block 11 is located between the V-shaped groove 10 and the bidirectional screw 7.
[0028] The wall of the tee pipe is locked inside the cavity of the V-groove 10, thereby improving the stability and contact area of the clamping plate 5 in holding the tee pipe; the stop block 11 can limit the clamping position of the tee pipe and prevent the tee pipe from contacting the bidirectional screw 7.
[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the two rotating rods 301 at the top layer are fixedly connected to support blocks 12, and the support blocks 12 are in contact with one side of the device body 1.
[0030] Support block 12 is used to improve the stability of the movement and use of the rotating rod 301.
[0031] like Figure 1 and Figure 2 As shown, an angle scale is engraved on the upper part of the device body 1, and an arrow is engraved on the movable end of the rotating rod 301;
[0032] The arrows indicate the angle between two adjacent openings of the tee pipe.
[0033] like Figure 1 and Figure 3 As shown, both ends of the bidirectional screw 7 are fixedly connected to a first rocker arm 13, and the movable end of the worm gear 9 is fixedly connected to a second rocker arm 14. The second rocker arm 14 is located on one side of the device body 1.
[0034] By rotating the second rocker arm 14, the worm gear 9 rotates; by rotating the first rocker arm 13, the double-ended screw 7 rotates.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
